Like you I’ve been fascinated by what others believe and why and picking holes in their beliefs as well. Not to convince them they’re wrong, of course, but to challenge their beliefs. I’ve never seen religion as untouchable and I haven’t met any who do. I’ve heard of them but I’ve never met them.
Lately, my attention is shifting away from debates of whether God exists but rather to why science seems to be accepted as the best way to determine that once and for all. I’ll need to meet up with you again soon, ’cause I can’t think of anyone with whom I’d rather argue it.
