This kind of sums it up...
"Fundamentalism demands believers, not thinkers. The powerful fundamentalist belief system prevents converts from examining information presented by any source other than its own. Knowledge from other sources is condemned as "dangerous to the faith."
Fundamentalists are convinced that liberal scholars want to wipe out religion. True believers must stand firm against compromise, be on guard against worldly thinking and secular learning, holding to revealed truth.
The net effect: fundamentalism favors stability over innovation, predictability over experimentation, conformity over original thought."
