I started following thread when it was first posted, got busy, and then came back it was 12 pages long...so I'm starting a new one.
Last night in my psych of religion class (which is incredibly fascinating, btw), I learned this:
"Fundamentalism" is a 20th century phenomenon. It means that the believer has boiled down his beliefs to 5 fundamental beliefs:
1. Inerrancy of the Bible
2. Virgin birth
3. Substitionary atonement of Jesus.
4. Body Resurrection of Jesus.
5. Authenticity of Christ's miralces and a pre-millenial second coming.
Reducing the body of Christianity down to these basics in scientific terms called reductionism. It's an over-simplification that disallows for complex and abstract thinking. So - you get a fundamentalist who is faced with direct contradictions either within the Bible or with something in the Bible and something provable by science (i.e. earth created in 6 days vs scientific fact that it's been around for millenia) and they are not psychology capable of complex abstract thinking and revert back to the fundamental thinking. They simply are incapable of accepting anything else.
For example, last night my professor pointed out some very basic discrepancies in the Bible - there I was, looking at the two verses side by side and I was blown away. How many hundreds of times had I read the same thing and NEVER put it together that there were differences? I believed what I believed and simply did not see anything different.
So, in my opinion, fundamentalism IS inherently dangerous because it doesn't allow for the natural development of abstract reasoning and logical thinking.
Another interesting thing we learned is that religious identity is usually not connected with belief, but rather because of the social connections. Belief/commitment follows (thus the success of love bombing and shunning). It seems to me that faith is rather simplistic - I believe it because I believe it - and I don't care what else you have to show me (stomps imaginary foot). It's thinking that requires complexity and the ability to reason and make good belief-based decisions.
