There is a great line in the Ben Affleck movie The Accountant, wherein Ben's father (Ben plays an autistic savant) tells his boys, just as they are about to take a bunch of bullies, that "people don't like different." Religion and power are ever used to demonize "different;" all you have to do is follow the money. I daresay very few people really understand how much we are manipulated to like, dislike, hate, disapprove, fear, etc. each other. There is no profit in peaceful coexistence, David.
