Both got a point, and miss one.
I'll bet money you are incorrect. They do not believe in Satan. Contact the COS, and they'll confirm what I'm saying. There's no use discussing this anymore until you actually contact them.This is true but satanism doesn`t neccesarily equal LaVeys group, wich is atheistic, one might call it magical hedonism perhaps, some say humanism would be better name than satanism. Other groups like Temple of Set do, in some way. Their website is kinda cool:
http://www.xeper.org/. CapteinPungent has got a point thogh, but actually only concerning satanism from a christian point of view(the terminology is usually
christian satanists ), wich is quite rare or non-existent, not from the point of view of the majority of
those who choose to call themselves satanists. All you have to do is think he`s a cool character, I guess. Philosophy might agree but the science of religion will not:)
