In my case at least it has nothing to do with contraception. It has everything to do with correctly interpreting the bible.
Is there only one correct interpretation? It's really funny (as Mrs. Don-o keeps pointing out) that your interpretation is so different from that of the vast majority of interpretations offerred by Jewish and Christian scholars over thousands of years.
If I found myself in that situation, it would really bother me. I would begin to wonder if it were possible for all those other interpreters to be right, and me to be wrong.
