He said he considers it borderline evil NOT to believe in the innate superiority of himself.
I consider it border-line evil to think that other people deserve worse treatment than myself. If you actually are, say, a woman in Saudi-Arabia and you're fine with not being allowed to drive, running the risk of execution for infidelity and so on, that's one thing. But if you're enjoying my culture, you're damn well going to defend it too. I dislike the hypocrisy that is usually required for cultural or moral relativism.
