I think it is time for another discussion of the differences between correlation and causation. In Racine there is an unfortunate correlation between dark skin and poor academic achievement. And unfortunately, some have no doubt concluded that the former causes the latter. Not so.
So what is the cause of the academic failings among Racine's black students? In my view, there are two primary causes. First, there is a subculture in Racine and elsewhere that infects many in the black community. This defeatist subculture glorifies violence and misogyny, rejects academic achievement and blames the larger society for the inevitable failures. Second, there are educators, most of whom know full well that there are cultural problems that are brought into the classroom, but they can't act accordingly toward their students. Why? Because teachers are silenced by their own liberal philosophy of multiculturalism, wherein all cultures are to be equally valued and validated. Rather than challenge the harmful culture that results in failure, teachers instead join forces with said subculture and blame the larger society for all the problems.
So for a black child to succeed in Racine, he may well have to reject the culture of the neighborhood and reject the enabling attitude of his teachers. Good luck with that kids!
