I don't know about most, but certainly some. :)

You're quite right that "people are moved by a very personal, subjective experience of God, or what they imagine God is." I think that's fine. It's not these "amorphous" types who resort to cruelty and violence. It's the doctrinaire.

I do worry every day that civilization will be destroyed by gangsters enabled by religious fanatics but feel helpless to do anything about it. Appeals to reason, evidence and common decency simply crash against the wall of certainty of those who believe God is on their side. So it's ever been.
