The thing that concerns me more than anything is when anybody becomes closed off and exclusive of other people's ideas. All of our brains are in the same mode of searching when trying to understand reality, and when we come to a belief system that makes sense to us we hold it strongly, whether it's an atheist view, or a Christian view, or a Muslim view, whatever, then it's very hard to let go and I think it's so important to try to foster dialogue.
