Deep down, do you think most religious people really believe what they are peddling? Or, do you think there is a lingering fear or knowledge that they are wrong?
I think people who get "possessed" or the holy rollers that throw themselves onto the ground or those that hear voices... they must know they are acting. Right?
I also hypothesize that the ones most insecure in their beliefs are also the ones that scream it into the hills and wear it on their sleeves. Like, they are looking for confirmation.
These are just my own thoughts on the matter. Yours?
