Well magic doesn't imply a God, so you could be atheist and satanist, somehow, based on your definitions. Your last statement is just wrong. Now you're talking about skepticism.
How is my last statement wrong? You cant belive in satan or his magic and be an atheist. I guess you can be an atheist and belive in magic but then you are a motherfucking stupid atheist.
Go do your homework please.
The Nine Satanic Statements
from The Satanic Bible, ©1969
by Anton Szandor LaVey
1. Satan represents indulgence instead of abstinence!
2. Satan represents vital existence instead of spiritual pipe dreams!
3. Satan represents undefiled wisdom instead of hypocritical self-deceit!
4. Satan represents kindness to those who deserve it instead of love wasted on ingrates!
5. Satan represents vengeance instead of turning the other cheek!
6. Satan represents responsibility to the responsible instead of concern for psychic vampires!
7. Satan represents man as just another animal, sometimes better, more often worse than those that walk on all-fours, who, because of his “divine spiritual and intellectual development,” has become the most vicious animal of all!
8. Satan represents all of the so-called sins, as they all lead to physical, mental, or emotional gratification!
9. Satan has been the best friend the Church has ever had, as He has kept it in business all these years!
From the evleven satanic rules:
7. Acknowledge the power of magic if you have employed it successfully to obtain your desires. If you deny the power of magic after having called upon it with success, you will lose all you have obtained.
Now please shut the fuck upp. Satanism is not atheism. If you dont belive in a god you are an atheist not a satanist, you cant be a satanist and atheist.
