Heh. No...no supernatural beings for me. There are basically two camps in Satanism--some people view Satan as a deity (although I believe they're in the minority), and for others, it's more a philosophy than anything; it doesn't require any specific beliefs. It's largely a "joke" religion, handling real philosophical concerns with a heavy dose of sarcasm.
I was reading over some old posts in the politics thread, and I saw this in one of your posts:
"Would you vote for candidate Z even though he's Jehovah's Witness?"
I understand the point you were trying to make about the irrelevance of a political candidate's religious beliefs, but strictly for the sake of accuracy, I'd like to point out that JW's are banned by their religious leadership (The Watchtower Organization) from participating in government in any way. That includes voting, holding political office, serving in the military, or even saluting the flag. According to them, doing such things would be directing worship towards the government and making the state into an idol. Weird, I know. I just thought I'd point that out.
