Racism is not the right word, it's not a matter of race, it's selfism, you are not enough like myself and I feel insecure in my self. Therefore the component most unlike my self in you is what I hate. Language, race, religion, sexual preference, whatever, it's all the same, people will find something to hate over, something that differs the self from the other, make up their own differences if they can't really find them, a la Shelbyville/Springfield.
