i will go ahead and presume you are talking about right wing christian fundamentalism.
if i am wrong, i apologize in advance.
in my opinion it is the rabid, paranoid funamentalism from the "other side" of the right wing Chrisitan position that put us in the mess we are in. The dogmatism of the Christian Right has always been the same and never changed. A steady diet of Biblical principals. And beofre the Liberal Left began shaking things up, and kicking God out of Scchool and country, everything seemed to be sailing along rather nicely.
