you make an interesting point; however, it is not the same thing of a person to say negative about their liking and about their (color) race/nationality. They can be similar, but not the same. For instance, the one who likes a certain object/living form, but the other does not like him/her precisely because the person liked that certain thing, is known as discrimination. As for a person who hate the people by their different skin color, language, religion, or nationality, are known as racist. Both these word are a form of prejudice. Another way would be stereotyping. My point is, you would probably see those kind of people everywhere and anywhere. Anyway, despite my randomness entrance to a stranger, I really love to state out my opinions especially if the statement is worth my timing.
