Is It That Hard

I get that conservatives want to downplay the existence of racism, but is it really that hard to admit that in a country of 320 million there might be a few homocidal racists? I haven't even seen many liberals (or others) try to link the Charleston shootings to mainstream conservatism in any way, whether or not that's valid (ok, it's valid, but it's slightly complicated). It'd be one thing if the mainstream discourse was filled with people blaming Rush Limbaugh and conservative politicians for what happened, but I haven't even seen that really. It's as if the simple existence of racism is an indictment of brand conservatism. And, you know, it probably is, but it isn't as if that many people with prominent platforms are actually making that case. Defensive much?
