And you seriously fail to understand FACTS. So let me just highlight the facts that you seem to be missing here:
LaVeyan Satanism is a philosophy (not considered a religion by many of its followers) founded in 1966 by Anton Szandor LaVey. Its teachings are based on individualism, epicureanism, and "eye for an eye" morality. Unlike theistic Satanists, LaVeyan Satanists
are atheists who regard Satan as a symbol of man's inherent nature.
The Symbolic Satanist
views Satan as a fictional, mental/mythic archetype, and admire the character as the "Adversary" or the "Light-bringer"
One cannot be an atheist and a theist at the same time (because they are mutually exclusive. One CAN be an atheist and a Satanist at the same time because Satanists don't necessarily believe in the existence of God, gods or Satan. And that's all that's required (by definition) to be an "atheist". What part about that are you not understanding? :sarcastic
Be that as it may, this fact is irrelevant as it fails to justify the error in your logic. Theism is not determined by whether or not a philosophy is based on a religious figure. It is determined by whether or not someone believes in God or gods. Therefore, until you can establish that Satanists believe in God or gods (regardless of what religious figures their beliefs are based on), you are still WRONG.
