back to the church, if you ever have kids, the Unitarians typically have a great Sunday school program that gently teaches a lot of philosophical stuff and encourages kids to think through the "big questions"
I got a brief exposure to what they have the kids do. It was honestly astonishingly good. They were having age groups vote on study units of other world religions so they could learn history, teachings, and culture from a really broad base. When I walked in one set was talking about Calvinists pretty openly and another was working on some indigenous animist stuff. I came away thinking that these kids might be totally impervious to someone telling them only one religion had the answers simply because they had way too much context from such a young age.
Was honestly jealous.
