Hi there...
just thought i'd add a bit here...
when I was about 16, I went through the whole 'Satanist" thing- more as a way of exploring being a teenager than anything else. It really isnt as bad as what some people think.... and I dont follow that path of thinking anymore- But I think it was a stage for me.
That said- I do have a copy of 'The Satanic Bible' by Anton la Vey- which is what true satanists believe. Makes for interesting reading- for about 5 minutes!

Not much different from declaring one's religion as 'Jedi' really...
