Not what I said but don't let the facts stand in the way of your strawmen.
If pointing out that the black community has a cultural problem that is holding them back equates to "white supremacy", then I might as well be the Grand Wizard of the KKK because I hold that belief more fervently than any other American sociological concept (off the top of my head).
At some point, you and your ilk, are going to have to explain how the wife and best friend, both born very poor in communist countries, with a native tongue other than English, with parents who don't speak English, end up outperforming the average black person born in the US without appealing to massive cultural differences (hint: that's the answer). Poverty? They grew up poorer. Advantages? Their parents don't speak the native tongue and English isn't their first language. Institutional racism? They went to the same schools and outperformed their peers. Same in the workplace.
Then there are the kids I went to school with. When the school published test results by race, Asians did the best, followed by whites, then Hispanics (almost all of whom English is a second language and non-existent at home), then blacks. Same community, same schools, same teachers. You are left with three options:
1) Grand Conspiracy
2) Genetics
3) Cultural differences at home
Take your pick. Anybody with a brain and intellectual honesty knows the answer.
Then again, I'm just a White Supremacist. You know, the same White Supremacist who choose to have a best friend and marry outside of my race. If anything, you'd have to say I'm an Asian Supremacist or self-loathing White Supremacist because I think Asian culture is, on the average, superior; but I'd imagine that doesn't fit into your real agenda which is about how the white man is the devil and the black man is their biggest victim here in 21st century.
