What is your opinion on Levayan Satanism. Just to be clear, LeVayan satanists are atheists, and they don't believe in an actual satan. The character of Satan, who they regard as fictional is a symbol of indulgence, vengence instead of turning the other cheek, etc. After reading about the core values, I found that I didn't find anything I disagreed with, but I have no wish to identify myself as a satanist. They see themselves as a religion, although I do not, and I j=don't particularly feel the need or desire to associate myself with any religion.
What do you think the pros and cons are to identifying as a Satanist rather than just as an atheist?

For reference, here are the 11 Satanic Rules of the Earth:
Do not give opinions or advice unless you are asked.
Do not tell your troubles to others unless you are sure they want to hear them.
When in another’s lair, show him respect or else do not go there.
If a guest in your lair annoys you, treat him cruelly and without mercy.
Do not make sexual advances unless you are given the mating signal.
Do not take that which does not belong to you unless it is a burden to the other person and he cries out to be relieved.
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.
Do not complain about anything to which you need not subject yourself.
Do not harm little children.
Do not kill non-human animals unless you are attacked or for your food.
When walking in open territory, bother no one. If someone bothers you, ask him to stop. If he does not stop, destroy him.

And the nine Satanic Statements:
Satan represents indulgence instead of abstinence!
Satan represents vital existence instead of spiritual pipe dreams!
Satan represents undefiled wisdom instead of hypocritical self-deceit!
Satan represents kindness to those who deserve it instead of love wasted on ingrates!
Satan represents vengeance instead of turning the other cheek!
Satan represents responsibility to the responsible instead of concern for psychic vampires!
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!
Satan represents all of the so-called sins, as they all lead to physical, mental, or emotional gratification!
Satan has been the best friend the Church has ever had, as He has kept it in business all these years!

I'd like to know what you all think.
