This guy called Martin Luther King. You should look him up. He had a few interesting ideas. In fact, the line you quoted Is a link to his speech.
As for "obsessive racial focus" I mean that constantly monitoring the relative proportions of black/white/asian people in various fields is not the anti-racist utopia any sane person wants. Not least because equity, the goal of ensuring that these proportions are reached and maintained, incorrectly assumes that racial groups are all the same.
This might be more often the case in a world where we erased everybody's memory and removed all traces of history and culture, but in this world, black people and Asian people and white people make different choices for reasons that are not just attributable to racism or socioeconomics but traditions and culture.
And lastly, racial identities, as I refer to numerous times, is the idea that "black people" are a solid homogeneous group who are in competition with and "white people" who are another homogenous group.
This trivially false idea is the root of all racism. It's the reason people talk about "black homicide rates" and "black-on-black crime" and "black IQ". It's why people get wrapped up by "white nationalism" and "white power" and "white supremacy." If you dislike these concepts, as I'm sure you do, understand that the only way to move past them is to stop thinking this way.
Black people, like white people, are people. And while it's true that we haven't had a society where people are treated without respect to race in the modern world, that for any sane person, is the goal.
