"Eventually, you pick a relatively relaxed “normal” religion, complete with all the “God” stuff. You don’t believe everything they say is literally true, but our reality is strange and inexplicable, so who knows? There’s a great stable community and you talk about the broader themes of life and you’re healthier and happier.
You secretly guess that the group is sustained by a minority of true believers who make up critical mass for a larger group of people like you, but you never talk about this and neither does anyone else. When you have kids, you feel weird about explaining your thoughts about all this to them, but you don’t parrot back what the religion says when you’re talking about the meaning of life either."
This isn't a democrat or republican thing though, you can totally join a Democratic church, with a strong community, but they are largely minority churches.
They are also still generally conservative.
