Whites destroyed black culture. They then systematically suppressed any attempts by black people to rise. Culture is birthright, and once it's destroyed you have destroyed a person's greatest asset.
There was never a "Black culture" There were many different, competing cultures. Some had been advanced at some point in history, but with the exception of Ethiopia and Somalia, sub-Saharan Africans didn't even use the wheel before Europeans arrived.
I'm not going to get into a slavery debate here, but African Americans have it so much better than they would have had they had no contact with other races.
Black culture.... We saw it Sunday at half time.... and later at the press conference.
