If the fundamentalists are a problem, maybe there’s a problem with the fundamentals?
Obviously religious people remain the vast majority and being a good person or not is largely disconnected from religiousness. It’s difficult for me though to not think that a religious person’s reasoning is broken in some way, and to be more skeptical of how they verify ideas in general.
If they can’t get something basic right, why would they be right about something more complicated?
A lot of the rationalization of religious people is complicated in a way that suggests they have some underlying idea of what the accurate world model is (they just want to believe otherwise): https://www.lesswrong.com/posts/CqyJzDZWvGhhFJ7dY/belief-in-...
One thing I credit the internet for is allowing me to read and learn enough to escape it. I think most people will end up with whatever belief system they grow up surrounded by.
