My father was a non-practicing Catholic, my mother Methodist and they chose to be married by a Justice of the Peace and never christened/baptized my brother or me. My brother is fine with no contact with religion at all (he's undiagnosed AS) and I've explored one religion/denomination after another. Recent reading I've done suggests that it's fairly common for female aspies to "try on" a variety of religions before settling on one, if they ever do. (I did.)
For some people I think religion is a matter of belonging somewhere, wanting to fit in somewhere that seems somehow socially acceptable. "Socially acceptable" doesn't really mean anything to me, though. I just have boundless curiosity.
The exclusionary aspect of religion is what infuriates me... the kind that says 'if you don't agree with us you're on the way to hell for sure' is the worst. Who are they to say/know they're right, right?
That said, I chose to go to a Disciples of Christ seminary some years ago and was the only non-Christian there. Disciples are very, very accepting! I was working with dislocated workers (people made redundant at work) and here in the buckle of the bible belt in the USA, many would tell me they weren't just looking to get another job where they'd just be downsized again but instead wanted to find some kind of 'higher purpose' in their work. In other words, they'd open a conversational door that involved their religious beliefs and even with an MBA I didn't feel I had the qualifications to go through that door with them. Going to the seminary helped me with that, although a car wreck happened before I got the M.A. in pastoral counseling for which I was enrolled.
Religion is an intensely personal issue, and talking about it can be as divisive as race, politics and ethnicity. I think of the religion I chose as the language I use to talk to the god of my understanding and I never, ever, ever, never (etc.) try to convince anyone that belief or disbelief is either right or wrong...
