Who appointed white people the "experts" on the black race (especially in America)?

White people in America seem to think that they are experts on the black race. They think they know EVERYTHING about the black race, but probably can't tell Malcolm X from Louis Farrakhan. White conservative racists love to say that blacks are Democrats because "they need to be on the plantation" even though they can give absolutely no evidence. News flash: Blacks vote Democrat because white racists (ahem, SOUTHERNERS) all vote Republican and Republicans would re-instate slavery if they could.They also like to promote any black race traitor (read "Black Republican") to a nearly angelic status (Condoleeza Rice, Hermain Cain, etc.).
