0. Intro
The announcement of Uniswap v3 is no doubt one of the most exciting news in the DeFi place recently 🔥🔥🔥
While most have talked about the impact v3 can potentially bring on the market, seldom explain the delicate implementation techniques to realize all those amazing features, such as concentrated liquidity, limit-order-like range orders, etc.
Since I’ve covered Uniswap v1 & v2 (if you happen to know Mandarin, here are v1 & v2), there’s no reason for me to not cover v3 as well ✅
Thus, this article aims to guide readers through Uniswap v3, based on their official whitepaper and examples made on the announcement page. However, one needs not to be an engineer, as not many codes are involved, nor a math major, as the math involved is definitely taught in your high school, to fully understand the following content 😊😊😊
If you really make it through but still don’t get shxt, feedbacks are welcomed! 🙏
There should be another article focusing on the codebase, so stay tuned and let’s get started with some background noise!
1. Uniswap & AMM recap
Before diving in, we have to first recap the uniqueness of Uniswap and compare it to traditional order book exchanges.
Uniswap v1 & v2 are a kind of AMMs (automated market marker) that follow the constant product equation x * y = k, with x & y stand for the amount of two tokens X and Y in a pool and k as a constant.
Comparing to order book exchanges, AMMs, such as the previous versions of Uniswap, offer quite a distinct user experience:
AMMs have pricing functions that offer the price for the two tokens, which make their users always price takers, while users of order book exchanges can be both makers or takers.
Uniswap as well as most AMMs have infinite liquidity¹, while order book exchanges don’t. The liquidity of Uniswap v1 & v2 is provided throughout the price range [0,∞]².
Uniswap as well as most AMMs have price slippage³ and it’s due to the pricing function, while there isn’t always price slippage on order book exchanges as long as an order is fulfilled within one tick.
In an order book, each price (whether in green or red) is a tick. Image source: https://ftx.com/trade/BTC-PERP
¹ though the price gets worse over time; AMM of constant sum such as mStable does not have infinite liquidity
² the range is in fact [-∞,∞], while a price in most cases won’t be negative
³ AMM of constant sum does not have price slippage
2. Tick
The whole innovation of Uniswap v3 starts from ticks.
For those unfamiliar with what is a tick:
Source: https://www.investopedia.com/terms/t/tick.asp
By slicing the price range [0,∞] into numerous granular ticks, trading on v3 is highly similar to trading on order book exchanges, with only three differences:
The price range of each tick is predefined by the system instead of being proposed by users.
Trades that happen within a tick still follows the pricing function of the AMM, while the equation has to be updated once the price crosses the tick.
Orders can be executed with any price within the price range, instead of being fulfilled at the same one price on order book exchanges.
With the tick design, Uniswap v3 possesses most of the merits of both AMM and an order book exchange! 💯💯💯
So, how is the price range of a tick decided?
This question is actually somewhat related to the tick explanation above: the minimum tick size for stocks trading above 1$ is one cent.
The underlying meaning of a tick size traditionally being one cent is that one cent (1% of 1$) is the basis point of price changes between ticks, ex: 1.02 — 1.01 = 0.1.
Uniswap v3 employs a similar idea: compared to the previous/next price, the price change should always be 0.01% = 1 basis point.
However, notice the difference is that in the traditional basis point, the price change is defined with subtraction, while here in Uniswap it’s division.
This is how price ranges of ticks are decided⁴:
Image source: https://uniswap.org/whitepaper-v3.pdf
With the above equation, the tick/price range can be recorded in the index form [i, i+1], instead of some crazy numbers such as 1.0001¹⁰⁰ = 1.0100496621.
As each price is the multiplication of 1.0001 of the previous price, the price change is always 1.0001 — 1 = 0.0001 = 0.01%.
For example, when i=1, p(1) = 1.0001; when i=2, p(2) = 1.00020001.
p(2) / p(1) = 1.00020001 / 1.0001 = 1.0001
See the connection between the traditional basis point 1 cent (=1% of 1$) and Uniswap v3’s basis point 0.01%?

But sir, are prices really granular enough? There are many shitcoins with prices less than 0.000001$. Will such prices be covered as well?
Price range: max & min
To know if an extremely small price is covered or not, we have to figure out the max & min price range of v3 by looking into the spec: there is a int24 tick state variable in UniswapV3Pool.sol.
Image source: https://uniswap.org/whitepaper-v3.pdf
The reason for a signed integer int instead of an uint is that negative power represents prices less than 1 but greater than 0.
24 bits can cover the range between 1.0001 ^ (2²³ — 1) and 1.0001 ^ -(2)²³. Even Google cannot calculate such numbers, so allow me to offer smaller values to have a rough idea of the whole price range:
1.0001 ^ (2¹⁸) = 242,214,459,604.341
1.0001 ^ -(2¹⁷) = 0.000002031888943
I think it’s safe to say that with a int24 the range can cover > 99.99% of the prices of all assets in the universe 👌
⁴ For implementation concern, however, a square root is added to both sides of the equation.
How about finding out which tick does a price belong to?
Tick index from price
The answer to this question is rather easy, as we know that p(i) = 1.0001^i, simply takes a log with base 1.0001 on both sides of the equation⁴:
Image source: https://www.codecogs.com/latex/eqneditor.php
Let’s try this out, say we wanna find out the tick index of 1000000.
Image source: https://ncalculators.com/number-conversion/log-logarithm-calculator.htm
Now, 1.0001¹³⁸¹⁶² = 999,998.678087146. Voila!
⁵ This formula is also slightly modified to fit the real implementation usage.
3. Concentrated liquidity
Now that we know how ticks and price ranges are decided, let’s talk about how orders are executed in a tick, what is concentrated liquidity and how it enables v3 to compete with stablecoin-specialized DEXs (decentralized exchange), such as Curve, by improving the capital efficiency.
Concentrated liquidity means LPs (liquidity providers) can provide liquidity to any price range/tick at their wish, which causes the liquidity to be imbalanced in ticks.
As each tick has a different liquidity depth, the corresponding pricing function x * y = k also won’t be the same!
Each tick has its own liquidity depth. Image source: https://uniswap.org/blog/uniswap-v3/
Mmm… examples are always helpful for abstract descriptions 😂
Say the original pricing function is 100(x) * 1000(y) = 100000(k), with the price of X token 1000 / 100 = 10 and we’re now in the price range [9.08, 11.08].
If the liquidity of the price range [11.08, 13.08] is the same as [9.08, 11.08], we don’t have to modify the pricing function if the price goes from 10 to 11.08, which is the boundary between two ticks.
The price of X is 1052.63 / 95 = 11.08 when the equation is 1052.63 * 95 = 100000.
However, if the liquidity of the price range [11.08, 13.08] is two times that of the current range [9.08, 11.08], balances of x and y should be doubled, which makes the equation become 2105.26 * 220 = 400000, which is (1052.63 * 2) * (110 * 2) = (100000 * 2 * 2).
We can observe the following two points from the above example:
Trades always follow the pricing function x * y = k, while once the price crosses the current price range/tick, the liquidity/equation has to be updated.
√(x * y) = √k = L is how we represent the liquidity, as I say the liquidity of x * y = 400000 is two times the liquidity of x * y = 100000, as √(400000 / 100000) = 2.
What’s more, compared to liquidity on v1 & v2 is always spread across [0,∞], liquidity on v3 can be concentrated within certain price ranges and thus results in higher capital efficiency from traders’ swapping fees!
Let’s say if I provide liquidity in the range [1200, 2800], the capital efficiency will then be 4.24x higher than v2 with the range [0,∞] 😮😮😮 There’s a capital efficiency comparison calculator, make sure to try it out!

It’s worth noticing that the concept of concentrated liquidity was proposed and already implemented by Kyper, prior to Uniswap, which is called Automated Price Reserve in their case.⁵
⁶ Thanks to Yenwen Feng for the information.
4. Range orders: reversible limit orders
As explained in the above section, LPs of v3 can provide liquidity to any price range/tick at their wish. Depending on the current price and the targeted price range, there are three scenarios:
current price < the targeted price range
current price > the targeted price range
current price belongs to the targeted price range
The first two scenarios are called range orders. They have unique characteristics and are essentially fee-earning reversible limit orders, which will be explained later.
The last case is the exact same liquidity providing mechanism as the previous versions: LPs provide liquidity in both tokens of the same value (= amount * price).
There’s also an identical product to the case: grid trading, a very powerful investment tool for a time of consolidation. Dunno what’s grid trading? Check out Binance’s explanation on this, as this topic won’t be covered!
In fact, LPs of Uniswap v1 & v2 are grid trading with a range of [0,∞] and the entry price as the baseline.
Range orders
To understand range orders, we’d have to first revisit how price is discovered on Uniswap with the equation x * y = k, for x & y stand for the amount of two tokens X and Y and k as a constant.
The price of X compared to Y is y / x, which means how many Y one can get for 1 unit of X, and vice versa the price of Y compared to X is x / y.
For the price of X to go up, y has to increase and x decrease.
With this pricing mechanism in mind, it’s example time!
Say an LP plans to place liquidity in the price range [15.625, 17.313], higher than the current price of X 10, when 100(x) * 1000(y) = 100000(k).
The price of X is 1250 / 80 = 15.625 when the equation is 80 * 1250 = 100000.
The price of X is 1315.789 / 76 = 17.313 when the equation is 76 * 1315.789 = 100000.
If now the price of X reaches 15.625, the only way for the price of X to go even higher is to further increase y and decrease x, which means exchanging a certain amount of X for Y.
Thus, to provide liquidity in the range [15.625, 17.313], an LP needs only to prepare 80 — 76 = 4 of X. If the price exceeds 17.313, all 4 X of the LP is swapped into 1315.789 — 1250 = 65.798 Y, and then the LP has nothing more to do with the pool, as his/her liquidity is drained.
What if the price stays in the range? It’s exactly what LPs would love to see, as they can earn swapping fees for all transactions in the range! Also, the balance of X will swing between [76, 80] and the balance of Y between [1250, 1315.789].
This might not be obvious, but the example above shows an interesting insight: if the liquidity of one token is provided, only when the token becomes more valuable will it be exchanged for the less valuable one.
…wut? 🤔
Remember that if 4 X is provided within [15.625, 17.313], only when the price of X goes up from 15.625 to 17.313 is 4 X gradually swapped into Y, the less valuable one!
What if the price of X drops back immediately after reaching 17.313? As X becomes less valuable, others are going to exchange Y for X.
The below image illustrates the scenario of DAI/USDC pair with a price range of [1.001, 1.002] well: the pool is always composed entirely of one token on both sides of the tick, while in the middle 1.001499⁶ is of both tokens.
Image source: https://uniswap.org/blog/uniswap-v3/
Similarly, to provide liquidity in a price range < current price, an LP has to prepare a certain amount of Y for others to exchange Y for X within the range.
To wrap up such an interesting feature, we know that:
Only one token is required for range orders.
Only when the current price is within the range of the range order can LP earn trading fees. This is the main reason why most people believe LPs of v3 have to monitor the price more actively to maximize their income, which also means that LPs of v3 have become arbitrageurs 🤯
I will be discussing more the impacts of v3 in 5. Impacts of v3.
⁷ 1.001499988 = √(1.0001 * 1.0002) is the geometric mean of 1.0001 and 1.0002. The implication is that the geometric mean of two prices is the average execution price within the range of the two prices.
Reversible limit orders
As the example in the last section demonstrates, if there is 4 X in range [15.625, 17.313], the 4 X will be completely converted into 65.798 Y when the price goes over 17.313.
We all know that a price can stay in a wide range such as [10, 11] for quite some time, while it’s unlikely so in a narrow range such as [15.625, 15.626].
Thus, if an LP provides liquidity in [15.625, 15.626], we can expect that once the price of X goes over 15.625 and immediately also 15.626, and does not drop back, all X are then forever converted into Y.
The concept of having a targeted price and the order will be executed after the price is crossed is exactly the concept of limit orders! The only difference is that if the range of a range order is not narrow enough, it’s highly possible that the conversion of tokens will be reverted once the price falls back to the range.
As price ranges follow the equation p(i) = 1.0001 ^ i, the range can be quite narrow and a range order can thus effectively serve as a limit order:
When i = 27490, 1.0001²⁷⁴⁹⁰ = 15.6248.⁸
When i = 27491, 1.0001²⁷⁴⁹¹ = 15.6264.⁸
A range of 0.0016 is not THAT narrow but can certainly satisfy most limit order use cases!
⁸ As mentioned previously in note #4, there is a square root in the equation of the price and index, thus the numbers here are for explantion only.
5. Impacts of v3
Higher capital efficiency, LPs become arbitrageurs… as v3 has made tons of radical changes, I’d like to summarize my personal takes of the impacts of v3:
Higher capital efficiency makes one of the most frequently considered indices in DeFi: TVL, total value locked, becomes less meaningful, as 1$ on Uniswap v3 might have the same effect as 100$ or even 2000$ on v2.
The ease of spot exchanging between spot exchanges used to be a huge advantage of spot markets over derivative markets. As LPs will take up the role of arbitrageurs and arbitraging is more likely to happen on v3 itself other than between DEXs, this gap is narrowed … to what extent? No idea though.
LP strategies and the aggregation of NFT of Uniswap v3 liquidity token are becoming the blue ocean for new DeFi startups: see Visor and Lixir. In fact, this might be the turning point for both DeFi and NFT: the two main reasons of blockchain going mainstream now come to the alignment of interest: solving the $$ problem 😏😏😏
In the right venue, which means a place where transaction fees are low enough, such as Optimism, we might see Algo trading firms coming in to share the market of designing LP strategies on Uniswap v3, as I believe Algo trading is way stronger than on-chain strategies or DAO voting to add liquidity that sort of thing.
After reading this article by Parsec.finance: The Dex to Rule Them All, I cannot help but wonder: maybe there is going to be centralized crypto exchanges adopting v3’s approach. The reason is that since orders of LPs in the same tick are executed pro-rata, the endless front-running speeding-competition issue in the Algo trading world, to some degree, is… solved? 🤔
Anyway, personal opinions can be biased and seriously wrong 🙈 I’m merely throwing out a sprat to catch a whale. Having a different voice? Leave your comment down below!
6. Conclusion
That was kinda tough, isn’t it? Glad you make it through here 🥂🥂🥂
There are actually many more details and also a huge section of Oracle yet to be covered. However, since this article is more about features and targeting normal DeFi users, I’ll leave those to the next one; hope there is one 😅
If you have any doubt or find any mistake, please feel free to reach out to me and I’d try to reply AFAP!
Stay tuned and in the meantime let’s wait and see how Uniswap v3 is again pioneering the innovation of DeFi 🌟

成長的藝術 ◎露琵‧考爾(Rupi Kaur)著;張家綺 譯
⠀
十二歲我第一次覺得自己美
身體猶如一顆初熟水果
突然間
男人淌著口水瞅著我的初生臀
下課時間男生不想玩捉鬼
只想觸摸我的身體
那嶄新又陌生的部位
我不曉得如何駕馭
也不知怎麼坦然面對
努力想將它藏在胸腔裡
咪咪,他們說
我厭惡這兩個字
厭惡我說出這兩個字的尷尬
即使這兩個字指的是我身體
卻不屬於我
而是屬於他們
他們重複這兩個字
好像深思它的含意
咪咪,它說
讓我看看妳的吧
除了罪惡羞恥沒什麼好看
我試著腐爛陷入腳底泥巴
卻依舊杵在距離他那
勾起指頭的一尺之外
他俯衝上來啃噬我的半月
我咬了他前臂,好恨這副軀體
一定是我做錯事才會有它
回家後我告訴媽媽
外面的男人飢腸轆轆
她告訴我
我不能穿袒露胸部的洋裝
又說,男孩看見蜜果會飢餓
她說,我應該兩腿交叉坐正
這是女人該有的姿態
不然男人會氣憤動粗
又說,我可以避免這一切
只要我學習當淑女
問題是
這根本說不過去
我想不通為什麼
我得說服全世界一半人口
我的身體不是他們的睡床
明明我該學的是科學和數學
卻得學習身為女人該承受的下場
我喜歡翻筋斗和體育課,無法
想像兩腿夾緊走路
似欲窩藏某個祕密
彷彿接受我自己的身體部位
就等於邀請他們腦海起邪念
我不打算迎合他們的思想
因為蕩婦羞辱是性侵文化
處女情結是性侵文化
我不是你最愛商店的
櫥窗模特兒
不能任你隨意更衣,或
一旦被用過就丟棄
你不是食人族
你的行為不是我的責任
你有自制能力
下一次我去上學
男孩朝我後背吹口哨
我推倒他們
一腳踩上他們的頸子
挑釁地說
咪咪
那個眼神簡直太好笑
⠀
⠀
i felt beautiful until the age of 12
when my body began to ripen like new fruit
and suddenly the men,
looked at my newborn hips with salivating lips
the boys didn't want to play tag at recess
they wanted to touch all the new and unfamiliar parts of me
the parts i didn't know how to carry
didn't know how to wear
tried to bury in my ribcage
⠀
boobs,
they said and
i hated that word
hated that i was embarrassed to say it
that even though it was referring to my body
it didn't belong to me
it belonged to them
and they repeated it like they were meditating upon it
boobs
they said
let me see yours
there is nothing worth seeing here
but guilt and shame
i try to rot into the earth below my feet
but i am still standing 1 foot across from his hooked fingers
and when he charges to feast on my half moons
i bite into his forearm
and decide that i hate this body
that i must have done something terrible
to deserve it
⠀
when i go home i tell my mother
that the men outside were starving
she tells me i must
not dress with my
breasts hanging
said the boys will get hungry
if they see fruit
she tells me to sit with my legs closed
like a woman oughtta
or the men will get angry and fight
said i can avoid all of this trouble
if i just learn to act like a lady
but the problem is
that doesn't even make sense
i can't wrap my head around the fact that
i have to convince half the worlds population
that my body is not their bed
i am busy learning the consequences of womanhood
when i should be learning science and math instead
i like cartwheels and gymnastics
so i can't imagine walking around with my thighs pressed together
like they're hiding a secret
as if the acceptance of my own body parts
will invite thoughts of lust in their heads
i will not subject myself to their ideology
because
slut shaming is rape culture
virgin praising is rape culture
i am not a mannequin in the window of your favourite shop
you can't dress me up or
throw me out
you are not a cannibal
your actions are not my responsibility
you will control yourself
⠀
so the next time i go to school
and the boys hoot at my backside
i push them down
foot over their necks
and defiantly say
boobs
the look in their eyes
is priceless

NOTES ON CHARLOTTESVILLE:
OR, WHY WHITE PEOPLE DO NOT EXIST AS A PEOPLE
I've heard some several buddies, people I know well and care about (most of them not in comment boxes or in public) asking about the moral equivalency between the neo Nazis, white nationalists, and other white ethnostate type supporters and groups like Black Lives Matter, Antifa (short for Antifascists), and other direct action groups.
I'd like to speak to that comparison a bit and then turn to a more important part of it that I worry about. Before I get to that, I should first say that I've said enough about Trump. Honestly, the guy confuses me. He swings from a nihilistic idiot to a idiotic nihilist. His inconsistencies pile so high that you either get lost in them or you use them wholesale to try and make your point. He wins in the time and toll it takes. He also, I think, has found a very particular niche worldview for his newfound politics and is willing to, at the end of the day, embrace ANYONE willing to give him what he wants the most: affection. Never, at least to my memory, have we had a more emotionally needy president. But that's neither here nor there at the moment.
If you look at most social protests and revolutionary movements you will find a basic set of factions that don't change. They tend to spread between non violent oppositions and even less violent moderates, both winged by some type of pragmatists who are not in principle opposed to violence. Different sides will use the radicals of different parts of this division to throw away the entire argument of one side or another, and this is not an even equivalent exchange in the history of US racial tension. But I want to stay away, mostly, from broad historical claims here.
The point I am driving at is evident when we realize that the Civil Rights activists who practiced non violent acts of resistance were often lumped in with Black Panthers, or others not opposed to violence, although the two groups were ideologically fairly different. But I am not willing to say that they were so different as to not be judged as being on roughly the same side of the discussion. After all, the Civil Rights movement was not just the movement for the passage of legislation nor did it belong to the non violence of MLK Jr entirely. This is not historical. If you don't see that the US institution of slavery was a grave moral evil and that the Jim Crow laws that succeeded it were demonic in their formal and informal application, and that, as a result, those determined to end these things were in principle on the side of justice, then you really have no moral compass. Say what you will of the vast differences between MLK Jr and Malcolm X, but it is hard to argue that their social protest was off key in the tonic.
The more popular -- but equally as appropriate -- comparison these days is to Nazi Germany. (Of course, a great deal of the sentiment of the Civil Rights movement was a direct result of the effects that US wars had for those within its ranks who were not white, but that might be slightly off the mark in this case.) There is a bright and clear moral line between the Nazi ideology and its perverse Final Solution and those who sought to oppose it. This line, by the way, finds its way directly into the symbolism and rhetoric of the neo Nazi's at Charlottesville. Not only were there swastikas, there were Nazi crosses and other niche paraphernalia. There were the salutes, yes, but there were other salutations and insider ways of speaking going on. There were also the tiki torches, the modern Pepe Wal-Mart replacement for the burning torch rallies and burning crosses of the KKK. The grand knight of that sick group was standing by. They brought their own military-grade armed militia to protect those who came in homemade riot gear. This was not the making of a peaceful protest or free speech of the sort that we see the Westboro Baptists practice (not that they are emblems of public virtue, far, far from it!).
As I said earlier, if you find yourself unable to distinguish between Nazism in its original form and neo Nazis, white nationalists, and others like them and those who through what ever means they find useful (which one can disagree with in practice while still endorsing in principle) oppose them, then you are morally corrupt. If you can't quite figure out how the math works in this moral calculus, you are morally mindless and incompetent.
Of course, within any opposition to these (supposedly) easy immoral targets one can find many arguments and even passionate disavowals. But there are real moments when these lines are simply drawn and one must take a side. I have in the past even used the language of "alt left" in an entirely different usage, but I regret it deeply, now, seeing its life-cycle. I will not exchange my allergies to the ideological types of identity politics I have long opposed nor will my more specific critique of the critics settle. All that fuss gets set aside in these events. If I have to choose whether to stand next to a neo Nazi or Antifa, I'll choose the latter on pain of eternal damnation. To those who say you don't have to choose, that risk is one I am not willing to make. I would rather be a black panther than a lynch mob, as much as my truer sympathies lie somewhere else. Despite all my oppositions to modern warfare, I would pick up arms against the Nazis long before I'd "peacefully" cheer on their side. I think most people feel this way.
But something remains and this is what I worry about and even dread most: we are not fighting Nazis or lynch mobs. Most people would never go to march in Charlottesville. And even when you talk to many of the white nationalists they will say something along the lines of "I'm not racist." To them, their present politics is no longer that of the slaver or the KKK. They don't wear hoods and they don't want to own people as property anymore, it seems. They hate the Jewish people for reasons I am still not able to process in my mind, but their argument is more separatist than colonial -- so they claim.
They seem to think that the USA was founded by *their* ethnic ancestors, who hailed from Europe, gathered together in this ancient race called "White" that has recently, especially after the activism surrounding police brutality against African Americans, fallen into a disrepute that is sending the world into a globalist terror to come, in the biggest of the big governments.
Now, these conspiracy theories do not need to be true or believed to find where they hit a live nerve in a lot of people. Some people do ask why white people cannot have rallies for themselves without longing for ethic purity. Some people do think that white folks today are being washed away through interracial marriage, but many more who don't mind interracial romance still worry that white people are on the losing end of public sentiment. Lots of people who try to counter this tend to make it worse by appealing to gotcha replies about privilege or other things. I tend to find that too complex.
I recently commented to one of my friends that I don't think of myself as having very many "white" friends. Some of you might balk since many extremely intimate people in my life are, supposedly, white. And of course if we use one way of thinking about what "white" is, that is true. On the same logic, I would be, in certain real scenarios, white as well. But what I meant when I wrote to my friend was that I see my friends of European descent as from where they are. Those who don't know where they are from share with me a genealogical confusion that I can also understand.
Maybe this weirdness is partly because, on the vulgar ethnic analysis I am used to, I am neither white nor Black. And, of course, as many Africans who are neither black nor American will remind you, things become quite complex depending on what rules we are using to count the deck.
My point is this, and if you read nothing else, please read this: There is no such thing as "white people" in history. Most folks who use the expression were not allowed to use it only a few decades ago. The white supremacy of the KKK of old hated Blacks, yes, but also Mexicans, and Catholics, and Jews (of course), and atheists, and more. Depending on how you see it, whiteness was either more or less ecumenical, but just as ideologically religious.
Let me say it again: There will never be a "white ethnostate" based on European culture because the history of Europe is covered in ethnic feuds and wars. If you've never heard of a guy named Napoleon, check him out. I'm being serious. If you think of yourself as being "white" in some serious ancestral way, you're not. You are wearing a name tag your family was GIVEN at some point but never had by its own right. There are no white people in this familial sense. (Settle down critical race theorists, I am well aware of the whiteness that is real, too, but this ain't it.) There is no such thing as a white European culture or of a white heritage in that sense at all.
Again and again: The most scandalously false part of the neo Nazi mentality is as old as its previous, original half baked idea in Hitler's weak mind. The concept of a master race doesn't work for mastery of people nor does it work for figuring out who you really are. We come from places with names and languages and peoples and legacies that are concrete. Some of us lost a lot of memory at the hands of another, and others lost through the same hands. Today we tend to think that the ancestors of slaves, or indigenous peoples, or mixed-up mestizos are the ones who lack a strong identity and the rest have theirs in bold font. Not true. From your family to your soul, you don't really know who you are if you are using ideological pet words to hang the hat of your self.
I'm not a real Mexican and I'm not a real American -- and I'm no Canadian, either. My father was an orphan, so I've taken his bloodless name as my own, a Portuguese word by etymology. I of course will pass as a white guy at a Black family reunion, just as I passed as an indigenous guy today on the pier (until I produced a fishing license instead of a status card), just as I passed as an Iranian at a birthday party last week, and so on. But the real facts of who I am don't work in the abstract.
This is why if you want to find a better substitute for whiteness find a Greek Festival or an Irish Pub or a German Beer Garden or a French Restaurant. This is food and drink, and it is a set of multicultural cliches, but enjoy an Italian family dinner and tell me there is nothing about who someone is at stake there. The point is that the real identity we can and do celebrate is everywhere and it is not necessarily riddled with guilt, even if sometimes it could use some (or far less). None of it calls itself "white." None. If you are using "white" as your only name tag, then I am sorry to say that you've been fooling yourself. You don't have a people by that name. There is no such thing. Your great-great-great grandmother would mostly likely not answer to "white."
Personal history quickly becomes social, national, and regional histories and we find ourselves, again, at Charlottesville. All I can say for now about it, to my dear and beloved friends who I suspect think that they are "white," is this: We cannot have white rallies because there is no such thing as a "white" people. Black Lives Matter is not a movement for everyone who is of one dark color in the world -- it is about the US experience for those living within the legacy of slavery and Jim Crow over the past three years (some Black activist groups are critical of this aspect of BLM, by the way). If you want a "white" identity, then look to the folk expressions of it that we have and should treasure like music, food, and regional folk ways of being. Poetry, dance, dialect, accent, story. These are not safe or sanitary places -- I tend to think this story of a "white people" got made up there, too -- but they also don't pretend like people are any more or less related than they really are.
Donald Trump is a German-American man, not a white man. His whiteness is an entirely different issue that I am disinterested in getting into right now. If you wonder why white people are seen as bad sometimes, it is largely because of this false assumption: that white people exist as a people when they so manifestly do not.
