John Derbyshire has been fired from the National Review for an openly racist column on how white people should advise their children with respect to “blacks”: for the most part, avoid them. Because on the whole, they are unintelligent, antisocial, hostile, and dangerous. Or as he puts it, avoid “concentrations of blacks” or places “swamped with blacks,” and leave a place when “the number of blacks suddenly swells,” and keep moving when “accosted by a strange black” in the street. The language is alarmingly dehumanizing: black people come in “swamps” and “concentrations” (and presumably also in hordes, swarms, and just plain gangs). And it’s clearly meant to be a dismissal of the notion — much talked about recently in light of the Trayvon Martin shooting — that African Americans should be able to walk down the street without being shunned, much less attacked.
