Do people really lose their religion because of logic and reason? I’ve never seen this. There is usually some deeper story. If someone asks me why I don’t believe, despite being raised in the church, I’ll simply say it didn’t make sense and babble on about reason and logic if they push. This is just a shield to avoid sharing the truth with people I don’t trust on a very deep level.
Whenever I've met people who claim to have "reasoned" their way out of religion it has always been extremely shallow teenage rebellion, and always driven by feelings.
