I feel like a lot of people read the title and responded. The whole stance was perfectly reasonable including the portion about racism. It's more about what's not said than what's said. Take the expression "white trash" as an analogy. Given that there is no "black trash" "hispanic trash" etc. to go with it, the implication is that a white person of low socioeconomic status or education is trash among whites, while a similar person amongst other racial backgrounds is simply par for the course.
Similarly, failing to cite video games for black inner city violence implies a presumption that this sort of behavior is understandable for blacks, but requires a culprit when committed by whites.
