Slavery ended over 150 years ago. Generations of blacks have never been slaves in the U.S. Can't say the same thing about their ancestorial homeland where TODAY there are over 9 million slaves.
Asians had to deal with crushing discrimination, some of them even put into internment camps, yet you don't see any of them destroying our National Anthem, or continually wallowing in the discrimination they have faced. You don't see them VASTLY over-represented in criminal activity, or murders. They get themselves educated (which is not a dirty word to them, nor do they complain about it being "too white") and they out compete every demographic.
