Personally, I didn't stop believing because of the intolerances. I stopped believing because it was an obvious ancient attempt to control people that worked to various degrees but still has the dumb shit people thought was plausible back when they didn't understand much and didn't think there was any way to disprove their claims.
I think that is most people, I just asked why is everyone automatically accepting this as true. But there are two groups of religious people that I understand moreso: people who feel they witnessed or directly saw a miracle and people who like the experience of a religious group and being around the people in it.
