The issue is to what extent should it be used to rationalize despicable behavior in African-Americans.
Really? Because I haven't seen that idea introduced anywhere. Understanding the origin of a cultural phenomenom, is not "rationalization". Of course, talking to your enemy is not "appeasement" either, so maybe it's just that Americans are incapable of any sort of intelligent and/or empathetic thought wrt "other" people? I know that's a broad generalization, but it seems to hold true judging from this discussion board.
