This was an interesting read. Specifically Gnostic Satanism, Ophidian Satanism and Joy of Satanism.
Gnostic Satanism reminds me of Aristotle's Metaphysics (The word demiurge).
Ophidian Satanism reminds me of Enlightenment era philosophy because it focuses on freedom.
Joy of Satanism just sounds plain cool and plausible because I've always had the thought at the back of my head that all religious deities might actually be extra-terrestrials that visited Earth at some one point. (If you look at Hindu gods for example, they're all white and bluish looking.)
