Arab Blacks did enslave whites for centuries. The word "slave" comes from the word "slav." And yes we created beautiful civilizations afterward.

You ignore the fact that black Africans move HERE, all the time. Why are the moving here if we are so evil and racist and there is "institutionalized racism?" It's because the institutions actually favor functional black people, that's exactly what affirmative action is, an institutionalized policy of discriminating against white people. On average African Americans are the most prosperous of the entire African diaspora, including people in their native lands. You ignore the absolute tumult and violence that occurs when blacks get institutional power. See South Africa.
Baltimore city council https://goo.gl/images/1Dc7E9 Detroit city council https://goo.gl/images/13RUw2 Does that look like institutionalized racism to you? It's not, it's simply not.

I think you think that I have a high school education and I'm from the antebellum south. I'm not. I live in San Fransisco and I've attended the most far left universities you can find for more than a decade. I'm in academia. I am well acquainted with the idea of institutionalized racism, and I used to support this idea. I used to be an organizer against mass incarceration. I've probably read more bell hooks and Gloria Anzaldua than you have. I just don't think the facts support this worldview any longer. I looked for information that CHALLENGED my worldview, to see if it would stand up to challenge. The more I read, the more I realized it did not stand up to facts. You have the same opportunity and same responsibility.

I don't have an ignorance of history, or social forces. Far from it. I cannot google everything for you. I've supplied you with a lot of counterfactual information, but the rest is up to you if you are actually interested in truth. I don't want to hurt people and I don't want to treat people unfairly. I think telling black people (and white people) that black people's dysfunctional behavior is because of racism does a disservice to everyone. Racism exists, but it doesn't explain what we are seeing here. That Japanese for instance were recently interned in our country, and they are achieving very well. That doesn't mean I endorse multi-culturalism, but you need to test your hypotheses against other examples. Black people do worse in "anti-racist" school systems for instance, look at Berkeley high, a hot bed of anti-racist intersectional and feminist pedagogy for decades. Black students have the greatest achievement gap here than anywhere in the nation. Why is it that when this ideology gets hold black people achieve less and white people are less safe? I know you think your ideology favors "justice," but the functional outcomes of this ideology are the opposite.

If you want to improve the world for everyone, start with facts, not fear of the truth. Start with curiosity and challenge your moral assumptions. I'm going to end this here.
