Most Satanists see it as a gag and don't even believe in Satan, actually Atheists. The Church of Satan is more of a
cult surrounding sexual deviance than actual worship of the fallen one and they do not believe he is real.
I think Satan and Lucifer can be two seperate beings, with an entire kingdom of "demons" opposing
the Lord, look at Persian mythology with Ahura Mazda and his rival or brother Angra Mainyu, Persian and
Hindu myth are counterparts of each other.
Although, I do seem to imagine Satan as a more ancient being known as Samael, which I think is
the foundation of Satan to begin with, through various mis-translations and monotheism is general.
But as I mentioned the Kingdom and princes of Hell, and
demonology, which is really fun.
I'm not a worshiper but I find it interesting.
Also Space Satan,
It's hip, it's cool, it's trendy.
Hail Satan.
