I think the understandable and commendable outrage and rebellion of black Americans to slavery and Jim Crow and the widespread racism in the fifties and sixties was heartlessly exploited by white leftists. They established "revolution", Marxism, as the paradigm for black strength and progress.
Rice, Thomas, and Sowell are supposedly "sell-outs" to the resistence, lackeys of the white power structure, when in reality the Van Joneses and Barack Obamas are doing the bidding of the white leftist establishment. It's a tragic irony.
Very insightful!
