I know the Church of Satan identifies as being more atheistic than anything and they are against the belief that Satan is a real deity and don't want to be identified with actual Satan worshipers, same goes with some branches of Satanism (because some still worship and actively believe he is a real deity) but if you are going to claim you don't believe in any of it and that you aren't about the real Satanic stuff then what is the point of identifying with a religion/association that is named after Satan?

Wouldn't it just make more sense to follow another religious group or create a new one instead of labeling yourself a Satanist and constantly telling people you don't actually believe in Satan
