" So the first thing that happens in a conflict is that we choose a side, because that’s easier than trying to hold two thoughts in our heads at the same time. The second thing that happens is that we seek out facts that confirm what we want to believe—comforting facts, ones that permit life to go on as normal. The third is that we dehumanize our enemy. "
