DID YOU KNOW that a lot of people who have racism and sexism issues, or other bigotry or us vs. them issues such as "hating" anyone who doesn't have the same beliefs or political views, are just trying to make themselves appear TOUGH and "BAD-ASS"? When a person keeps trying to display hostility, they are trying to show dominance. Chimpanzees do this all the time but don't try to hide it. Humans do it all the time and try to rationalize that they're doing something else. It's exactly the same display, but humans have a couple more tools such as language and machinery that makes loud noises or are big and dangerous, and also of course sophisticated weapons. Chimps mostly use vocalizations and their bodies, sometimes sticks or rocks.
