Believing that one's own race is superior to all races, OR believing that one's race is superior to ONE OR TWO OTHER races, OR believing that another race is INFERIOR in some way, in ANY way, is all racism. If you are a human being, you are not exempt from any of these definitions. They apply to you and all of your friends and everyone you know, and every human being on Earth. If a person believes they are a better person than another because of their own race or the other person's, then they are a racist.
