Actually, Lavey considers any pagan religion to be Satanic ("The Satanic Witch"). So does Aleister Crowley, the real father of Satanism. I've dabbled in various religions from Christianity to Satanism and many pagan religions in between. Let me just say that every department has there own belief of what this symbol is or means and nobody can claim to know which idea is right (Or who invented Satan) unless they were there back when it began. If anybody was, I would like to hear about it.
