That sounds good, I think the Buddhists fit that, but how is it at excluding the border cases?
- Scientology
- Raelians
- Pastafarians
- Jedi
I don’t insist that they all be excluded, but what to do about groups with a made-up tacked-on cosmology that never-the-less probably has some true believers? (And cosmologies created by bronze age sheep flockers shouldn’t get a pass just because they’re old.)
