To me the most important questions to start with are these:
1. Are you following the beliefs handed down to your demographic through the centuries?
2. If so, how can you know/prove/presume that you would believe anything even remotely similar if you belonged to a different demographic?
3. If you recognize that the only logical answer to (2) is "I can't," have you examined the role of tradition and normative behavior in your community/family?
