Really? So none of your personal convictions, decisions, etc., are made on the basis of your religious beliefs?
Let's test that then.
What is your position on the following and why:
* Abortion
* Gay marriage
* Sex before marriage
* Transsexual/transgender rights
The problem is the evidence doesn't really support it; at least not when one adopts a rigorous standard for that evidence. I've often said that if fundamentalists required the same level of evidence they demand of science, they'd all be atheists.
However such beliefs are not typically adopted on the basis of rational evidence, but rather adopted for emotional reasons, personal fulfillment, etc.
