Picture a Satanist, and you might imagine someone dressed in a black cloak and masks engaging in bizarre, violent rituals involving the blood of dead animals and an inverted pentagram etched onto the ground in chalk. At some point, this vision, Satan might even burst through the floor in a flurry of fire and bring an end to the world. All in all, a Satanist is not the sort of person you’ll be calling up to have dinner with your mum anytime soon.
Genuine Satanism had nothing to do with the supernatural devil nonsense.
The primary and most persistent misconception about Satanism and Satanists is that we believe in and worship an anthropomorphic or spiritual being known as "Satan" or the "devil".
This is false.
We Satanists are atheists who adopt "Satan" as a symbol of passion, pride, liberty, and heroic rebellion in the tradition of the proto-Satanic themed poetry and writing of Giosuè Carducci, Lord Byron, John Milton, Benjamin DeCasseres, Mark Twain, and others that predate the founding of the Church of Satan.
Stating that one is an atheist leaf a lot of room for belief in a myriad of other spooky delusions unrelated to the existence of god(s) that are also regularly incorrectly packaged with Satanism.
