Why are people racist

People are exactly like animals, when they get hurt or harmed by a human they get a fear that makes response in there brains that makes them never get close to another dangerous person that can harm them. Well like us if we are harmed by someone or we see people getting harmed by a certain race or kind of people, we get a fear of getting hurt by that same race, we create like a respone in our brains that when we are close to a race that can hurt us we dont get that close so we can defend ourselves. We think that maintaining distance will help us, but the only thing that we do when we stay away from someone just because of there skin color, race, or traits, is that we lose one of the things that human beings need to survive, this is friendship. Everyone has some kind of racist beliefs, but some people develop it more than others or have a higher racist thought. Some people use racism as a weapon to defend themselves, they keep close to the people of the same kind because they are in their comfort zone. People are also racist because they are afraid of things they dont understand and are afraid to confront the way they feel.. So in conclusion we think that we never will understand the other races so we stay with a fear of getting hurt by other races, and when everyone in the world will stop thinking this way, the world will be a better place.
