I don't really know how to respond to all that. The violence in the Superdome was grossly exaggerated. There were no reported sexual assaults. That does not mean that there were none, only that visions of "lord of the flies" were inaccurate. Just facts. Or maybe non-concepts. Or whatever.
If you want to believe that there is no institutional racism (a concept that wearies me a good deal, but I don't deny it completely), like so many bubble-living white people, then go right ahead. And if you want to believe that some races have a "genetic predisposition for impulsiveness" (childish blacks!), then go right ahead. Knock yourself out.
I guess I will just continue to use non-words and non-concepts, whatever the hell that means.
