So there is potentially a religion in New Guinea that not seek to spread itself to willing minds to survive?
That would rock my entire concept of what the term religion actually means, as opposed to philosophy or just plain reasoning.
I think in a nutshell Badger was simply stating that people are people, and religion didn't change anything intrinsic about our properties as organisms.
I have to admit though, I've been having trouble seeing a difference in the rate at which the vector manifests itself in the darker desires of humanity - but this could just be because of the sheer volume of the population who carry it.
That's why I prefer philosophies and reasonings though, they don't pull guilt trips on you when you grow past them.
