I would argue that lots of white/black differences in America are actually due to distinct differences in the environment people of both groups were raised in.

I would argue that lots of white/black differences in America are actually due to distinct differences in the environment people of both groups were raised in. The only factor that makes it racial is the fact that in America, there are very clear and distinct subcultures that seperate whites and blacks if they so choose to be a part of those subcultures, and the socioeconomic properties / scoring on tests of their members are probably more indicative of the subculture's values rather than the quality of their genes.
