I've met several people like this and they always manage to drive me nuts. Once this girl in high school even stated straight to my face that "all homosexuals are perversed, sex-crazed and completely disgusting, they want to have sex with everything that moves and are always checking people out". I didn't even try to convince her otherwise since she was a complete a**hole anyway and clearly the kind of person who doesn't even want to consider the option she might be wrong. Plus she was a racist. Gosh I hated her so much, even thinking about that moment makes my blood boil.
It's delicious, isn't it!
