User blog comment:HumboldtLycanthrope/Any black metal, crust punk, or viking metal fans out there?/@comment-27007772-20150323180342

Satanism comes from before Christianity (unless you are speaking of LeVay Satanism, which is atheistic.) Theistic/Spiritual Satanism has roots in Babylonian times, with Baal-zebub/Beelzebub worship, and even Sumerian Belial worship. Both of which are beings in the religion. Christianity is the reaction, naming all demons after pagan gods to distill worship of them. (Satan, Odin, Leviathan, Azezal, all were deities in paganistic religions.)

Also, I listen to both Black metal and Viking metal regularly.
