Well, even if I can't remember what #3 was, I would still like to know what other people think makes an SMA religion. What should it have? What should it not have?
Can you have a "godless" religion?
Can you have an "anti-religion" dedicated to wiping out another specific religion?
Can you have a religion that worships a person, and not a god?
No
As long as there's some theology to go with the hatred, I see no reason why not.
Yes. Christianity already sort of does this, so it fits well.
