You claim to know some. I was raised one.

I went to a fundamentalist elementary school.
I went to a fundamentalist junior high school.
I went to a fundamentalist high school.
I went to a fundamentalist college.
I took courses at a fundamentalist seminary.

I've attended a score or more fundamentalist churches and am related to a good score or more fundamentalist believers. I have known THOUSANDS of fundamentalists.

I DO have a foot in both worlds. Your bigotry allows you the belief about the OTHER world that makes you most comfortable -- a view of that world from the comfort of your non-religious world.
