As Quentin Crisp pointed out more than fifty years ago, you can always tell a self-loathing closet gay because he'll be obsessed with condemning homosexuality. Republicans in general suffer from this problem, accusing their "enemies" of all the things they themselves are actually guilty of. It's basic psychology - pointing a finger at someone else in the hope people won't notice one's own issues - and it only works because most people are really, really obtuse.
