Dear edgy teens:
THIS is not the satanic cross:

THIS is the satanic cross (also known as the leviathan cross)

Also if you're trying to actually get into satanism read the satanic bible by LeVay. LeVayan Satanists are more popular and aren't actually theistic, but theistic satanism does exist. It's just not as popular, but we still use the satanic bible. There's also the temple of set, demonalotry isn't really satanism so much as "dark paganism"; dark paganism is people who believe in demons as old gods like how Baal was a god but Christians consider him a demon. Luciferianism is more theistic than satanism.
Don't hang out with the joy of satan crowd though; those people are actual anti-christians and everybody looks down on them for good reason.

LeVayan Satanism: 'Worship yourself"
Theistic Satanism: "FREEDOM!"
Demonalotry: "Christians call any other gods demons"
Luciferianism: "We call Lucifer the liberator"
