Personally, I can't claim to be one of them, but I have read their bible (by Anton LaVey). I read it back in high school when I was a Christian (believe it or not). I was actually very open to what they had to say because it all made sense to me. As I said, I can't claim to be one but I absolutely support most of their teachings. I can't really get into their rituals or anything, but their dedication to humanism and love of your fellow man/woman is something I can absolutely respect and get behind.

I don't have a problem with them at all. As far as I understand it, the only god they believe in is themselves, and to believe in oneself is sometimes the hardest thing to do, especially given the trying times that we're in where most people are still against we Atheists/Agnostics/Satanists/Etc. So they have my support despite the fact that their way of doing things doesn't 100% mesh with mine.
