I find it humorous that many of the Christians who get angry at you and this website start talking about Satan, when believing that a god probably doesn't (or just plain doesn't) exist means your feelings towards a satan are probably the same. Being a Satanist means you're believing in/worshipping something, and are therefore not an atheist. The Christians would do well to realize that theirs isn't the only religion, and that everyone else is not a godless Satanist.

Actually, lots of Church of Satan members are functional atheists. But even so, I see your point. Once, when someone asked me how it felt to work for Satan, I replied that if I were working for Satan I'd be making more money.
