This is a serious question. This is not troll bait. I do not intend to start a flame war or religious debate.
What I want to know is, why is it that professional psychologists do not consider religious belief some kind of mental illness or delusion?
If someone were to tell me they truly believed in little green gnomes in their garden, which I or they, could not prove or disprove, we would immediately classify this person as having some sort of delusion.
However, when given the same scenario, but replacing the little green gnomes with a god of their choice, not necessarily christian, it is generally accepted and they person is considered perfectly normal.
Could someone please rationally explain how belief in something unproveable in one case is perfectly acceptable, but a mental issue in another???
Again, keep the religious debates out of this, dont start flame wars, I want a real answer.
