How is that people like Christians and Muslims are against witches and Satanists, but they start horrible wars in the name of god and they really don't have a clue what Satanism is about, and all the other religions are about. I don't like religion period, but really what is the big deal? Just because some of these people do things that kill people ceremonially, but Christians kill people all the time in the name of the government. How is anyone on Earth better than the other? Who deserves to be in heaven or hell more than the other? No one is perfect.
