If you actually do the research, Satanism has nothing to do with any of those things.
Anton LaVey founded "LaVeyan Satanism" (which is what I am).
I don't really know much about Spiritual Satanism, but I feel like it's a bit evil and it may be what you think satanism is about. I don't know though, so don't take my word for it!
Anton LaVey pretty much says, in The Satanic Bible, that you should just be yourself, and don't give a rat's ass about what people think or say! THAT IS WHAT La Veyan SATANISM IS ABOUT. UGH.
I'm sick of the media thinking that Satan is some red, devil guy who lives in Hell. Guess what!
Again, Satanism isn't evil and mean and satanists don't fucking sacrifice people. Satanists don't sacrifice people because SATANISM IS AN ATHEIST RELIGION. GOSH.
Satanists don't believe in Satan or the devil or anything.
I forgot what else I was going to say because I got busy in the middle of doing this! Sorry! I will edit what I was going to say (if I remember what I was going to say).
