For me as an non-sectarian, the good parts from organized religion are advice and lessons about living life, which science doesn’t particularly address.
I recently read an elder theologist reflecting on the stages of enlightenment and I realized that I agreed entirely with them. The difference was our journeys for how we arrived at these same conclusions. They spent their entire life figuring that out. And I had figured it out probably by the end high school. I am not saying I am smart or flawless, because the other person has a lifetime of experience that I don’t have culminating in their wisdom. But they chose to spend their time on such matters, and I chose to spend my time differently.
Thanks for the book recommendation! Yeah, discrimination can happen with or without religion. It seems to me that any human system is capable of being exploited or corrupted.
I look at religion from the perspective of "what purpose does the manufacturing of religion serve?" assuming there's good intention. I am with you that what organized religion typically offers is not exclusive to religion.
What is "community"? Is it surrounding myself with people who are exactly like me?
Personally, I find it helpful to have a "safe space" to talk to other people who are going through a similar experience that I am. Although I am not great at it I also think it's healthy to interact with the outside world from time to time. At best we learn something from one another, at worst (I hope) we tolerate one another.
