The problem is that "Satan" is a direct figure from christian religion. Taking said figure and title and rearranging things to suit your viewpoint isn't even legitimate or credible. Which only makes the whole thing even more laughable. If you're going to worship the lord of the fallen, then own up to it. Represent. Don't puss out in order to maintain some kind of moral defense. That's just pathetic imo. The way you, and other new age satanists describe it is like a bastardized form of wiccanism peppered with narcissistic celebration- Baltard would love it.
Satan is a title from christianity, so to use said title but rearrange the characteristics of said figure whimsically like you are is silly. It's like me saying I'm a Thor-ist (w/e) but changing Thor's mythos to that of Buddha. Or that I worship Cthulhu but saying that we believe he wishes to bring bunnies and rainbows to mankind. All credibility and integrity is lost.
The way you describe him, Satan is a pussy.
Quoted for truth!
Also, those names are not all 'Satan'. As someone (I'm best described as a humanist agnostic, if you're asking) who's studied the Bible from back to front repeatedly- where 'Satan' first shows up, I can assure you that in that same context, for instance, that Leviathan simply means a great big sea monster, commonly believed to be a whale.
On the other hand, the biblical account of Satan isn't all that 'evil' in the modern sense- a lot of the 'pure evil' is from apocryphal sources and denomination specific belief that's led to the current popular culture Satan.
His biggest crime comes down to wanting to take God's place, believing he didn't need to follow God, and tempting everyone else to follow him.
Most of the actual destruction comes from God or through his actions.
It's important to note, though, that evil, to someone who believes in this God, is synonymous with sin- and so someone who sinned before humanity did and spends his existence getting humanity to sin is as evil as it gets.
Addendum:
Looking at the thread, it appears that there's something lost in translation with defining beliefs. Gorath's explanation on isms is how the academic English-speaking world views these definitions, and I suspect this might be different elsewhere.
