Nah. I'm a LaVeyan satanist. It's a branch of atheistic satanism. We don't believe in the devil, we use it as a symbol.
Basically, it's a religion of indulgence, rather then abstinence, as opposed to abrahamic religions. It says that we alone are our gods and that there is no heaven nor hell, and that we should make most out of our life here, because it's the only one. It has it's tenets and rules of the earth too.
Life is the great indulgence - death, the great abstinence. Therefore, make the most of life - HERE AND NOW ! - Anton LaVey
