Actually, most real satanists say that they don't actually believe in "satan," per se, as a spirit or demonic force. Instead, they just believe in the "principle" driving satanism, that of man's own greatness, etc. - "satan" is merely a figurative symbol they use. It is, in fact, more similar to Objectivism than many Objectivists are likely to be comfortable with.
"Man's reason is fully competent to know the facts of reality. Reason, the conceptual faculty, is the faculty that identifies and integrates the material provided by man's senses. Reason is man's only means of acquiring knowledge."
Ironic, since this statement itself is a faith-based statement that meets Mizz Rand's own definition of "mysticism," since there is no way it can ever internally verify itself.
Stuff-and-nonsense! Hasn't anyone read her work?!
This brings up yet another point - which is that a lot of people HAVE read her stuff - we just don't think it's any good. Frankly, I didn't need Ayn Rand to teach me a thing about liberty. Her books are stiff, obnoxious idiocy, and I frankly find it to be a terrible commentary on the intelligence and knowledgeability of American conservatives that so many of us think that we have to read Ayn Rand's books or watch some movie about one to "learn about freedom." Truly, Americans increasingly have no discernment.
That may be true, but you are idiotic if you think she's a Satanist (even with your tortured definition).
L. Ron Hubbard's philosophy was a naive kind of science-worshipping naturalism and rationalism brought to crackpot levels of extremism. In his philosophic outlook, 'mysticism' was the bad guy -- the corrupting influence on people which needed to be weeded out. And this meant Christianity, belief in God, etc., -- these parasitic beliefs cause all the problems in the world. This is much like Randism. However, Hubbard really was a satanist, for real. It is interesting to note that Robert Heinlein was a friend of Hubbard. Heinlein is a much loved science fiction author among libertarians and objectivists (and satanists too). All three: Hubbard, Heinlein, and Rand, used fiction as a vehicle for promoting their philosophies.
