let me just comment what Dean said cuz I'm too sleepy to write it in my own words
"The offical church of Satan doesnt even believe in Satan, they are a church made up of atheists, theist and agnostics working for social reforms and trying to help as many people as possible.
They use Satan as a symbol of rebellion, like rebllying against tyrannical governments and corruption organizations.
Some satanists legitmely believe in satan but almost none of them do anything harmful because of that and often they too focus on bettering the world
People hating of satanists is just as dumb as Islamophobia. Its just hating people for their beliefs and it often stems from a fundemntal lack of understanding of what the satanist believes, which is normally northing harmful."
mainly, satanists (from what I've heard) don't worship Satan, its just, y'know, a symbol. and their beliefs are usually just something along the lines of "I will treat others with respect, no matter their beliefs, culture, or background"
correct me if I'm wrong
