Here is more evidence towards our opposition to the classification of Devil worshippers as Satanists. According to this article, a fan of Black Metal band Surrender of Divinity murdered vocalist Samong Traisattha because he did not believe in Satan. The article explains that this motive for the killing was posted on a Facebook page likely by the murderer who apparently does worship Satan.
I’ve said before that theism of any sort can readily spawn a murderous madness and so once again a tragedy has been wrought by someone who believes in a supernatural entity and thinks he must act on its behalf. Satanism is an atheist philosophy and we consider it imperative that members of law enforcement worldwide understand that our rational, carnal philosophy does not support such deeds.
Satanists are not Devil worshippers.
