That’s a very shortsighted view of religion. People two thousand years ago were extremely religious and lgbtq friendly, etc. Most religious people are vaxxed. I mean the things you attribute ro religion is shortsighted, obviously so.
You’re looking at a small subsection of the world during a small subsection of time. It’s not applicable to religion as a whole and why people are religious. People are obviously not becoming religious in order to be antivax anti lgbtq, etc, etc. The reason is obviously not found there.
And no, we can not contextualize the human condition through rational thought. Humans aren’t just rational, we don’t just act rationally. We have irrational feelings, emotions and thoughts. So it’s literally impossible, in a literal sense. This is basic logic.
