could you explain what you mean by this part? Opens up a lot of questions!
Sure, I'll try, anyway!
More than that, it behaves this way because it's meant to, because it is designed to protect power, it's meant to avoid looking at real mechanisms and it's meant to fracture solidarity, it' meant to be bread and circuses.
Identity politics, or critical race theory, is a type of racial essentialism. To some extent you could compare it to ender essentialism. Our race is an essential part of our identity, from this view Racism is fundamentally disparities between races. So if you see a disparity, say in something like university education, it's caused by not recognising these identities as equal.
In this way of thinking, there is no questioning of underlying structures, and there is no critique of race itself. Both the leftist and conservative critique of racism, and the civil rights movement largely too, worked on a critique of race, and one that is based in history. That is, race was invented in order to justify economic oppression. The ultimate solution to solve racism, then, is to dissolve that concept. How to do that, conservatives and leftists disagreed, at least in part, but the observation that our perception of race was constructed was fundamental.
In the id politics conception of equality, because race itself is fundamental, equality and justice means lack of discrepancy between races on various measures. So as long at the % of blacks in university, killed by police, with degrees, heading companies, matches the general population, that is racial justice. But what you notice about this is what it really doesn't do is challenge the underlying problems, and especially not the economic system that needs exploitable workers at the bottom.
There are a lot of people with a strong interest in having exploitable workers at the bottom, and it no longer is very useful to them if they are defined by race. In fact it is useful to them to point to them being racially diverse, because that shows that the situation is just. So these people and organisations will tend to like these kinds of formulations. The Democratic party is the best example by a long shot, they can continue to be the party of the corporate sector and the 1%, and also claim to be the party of social justice. It deflects pressure on their paymasters by those with an interest in justice issues, their energies are being spent elsewhere.
It's not unimportant that it was after the uprising by black and white slaves in Haiti that African chattel slavery was introduced. And it's not unimportant that in the case of the the civil rights leaders, it was when they started to see the economic system as a whole at the root of the problem, many of them were radicalised, and began to make increasing moves to solidarity between groups and for workers, that you started seeing things like assassinations.
Reed has called this kind of race identity politics the lapdog of neoliberalism, and I think that's a useful image.
