The way to change people’s minds is to become friends with them, to integrate them into your tribe, to bring them into your circle. Now, they can change their beliefs without the risk of being abandoned socially.
Perhaps it is not difference, but distance that breeds tribalism and hostility. As proximity increases, so does understanding. I am reminded of Abraham Lincoln's quote, “I don't like that man. I must get to know him better.” Facts don't change our minds. Friendship does.
