Atheism

Okay good analysis. I'm certain Thelemites have come up with solutions to some of what you describe, but I'm not a Thelemite so I can't say what they are.

But it seems to me that your complaint with cults is essentially that they are religions, and that religion must always be abusive. If so, I see no need to pin the abuse on the word "cult".

Take Dalmatians. Dalmatians are black and white with spots, make for popular firefighter companions, and are all dogs. Because Dalmatians are dogs, we also know that they have four legs, fur, sensitive noses, wagging tails, and loyalty to humans. But these traits aren't traits of being a Dalmatian, they're traits of being a dog. If you point at a golden retriever and say "that thing has four legs and a tail! It must be a dalmatian!", you're wrong. It's a dog, and it shares dogness with Dalmatians, but not dalmatian-ness.

Likewise, if your complaint with cults is that they are religions and religions are abusive, there's no use calling religions cults just to point out their abuse. You'd be better off calling them religions.
