I'm going to assume that you typed that differently than you meant it. Because the implication that all racists are conservatives would make you look retarded.
If by "not to the same extent" you mean that the left doesn't get covered as much, then you may have a point. The fact of the matter is that both parties are nothing more than money and power machines. Those two items are the only things they actually care about. Neither side is more "socialist" or "racist" than the other; the political engines and media simply use those topics as carrots for votes. But they don't actually care.
And frankly, anyone spewing at the mouth about "republicans/conservatives" being "misogynistic/racist/homophobic", etc, is just as much an idiot as the half-wits spouting out about "jesus hates gays" and "Obama isn't American/is a Muslim", etc, etc. It's all fucking stupid, because anything based in "feelings", is inherently illogical and irrelevant.
