Again, I like your characters but I think you're missing one. The person who thinks that belief in [a] God is the result of rational and reasonable thought.

Or in any case necessary. That even if theism isn't the result of rational and reasonable thought, it is arational rather than irrational. Some religious people are aware that rational thought will drive towards atheism (for example) and will describe faith as a "choice", not unlike a moral preference.

Moral preferences are arational; rooted in biology and our social interactions, perhaps like theism where it is practiced.
