He's told me before that it's that I'm too quick to reach the conclusion that things like God, miracles, ghosts, etc. are BS without keeping an open mind because "nobody knows" and "there's no proof it's not real." Like he doesn't think I've actually thought about it and I'm just immediately shutting down the idea without any critical thinking just on the assumption that i know it all. I've tried to explain the total lack of evidence, the unicorn fallacy, etc and that a lack of proof against doesn't constitute a probability, but he still thinks I'm just pitting my opinion against equally valid opinions and assuming mine is better. I can understand how it looks that way, and I've tried to explain why I don't entertain the probability of spiritual things just because they're not empirically disproven, but he doesn't understand. So from his perspective I'm just being arrogant for the sake of being arrogant. I wish I had better debate/communication skills to explain my position better.
