Human beings can be devided into three races. They are black people, white people, and yellow people. In the past (and at present), how you are treated has varied greatly with how you look.Let me introduce each race. First of all, black people refers to the group of people whose skin is black. They were killed or abused or made slaves by white people. Their hierarchy was lowest. More recently, a picture book "The story of Little Black Sambo" was criticized as discrimination of black people. Second, white people were treated as the best of these three races. At last, I'll introduce yellow people. In fact, they as well as black people were abused by white people because they are colored rather than uncolored. In particular, Japanese, who are yellow were looked down on as "yellow monkey". I can't make sense why only your skin color determines how you are treated. The ideal is that everyone has the same status and the same abilities whatever their skin color is. However, the fact is not. Actually, I am a bit at a loss when I see a black person. These stereotypes, that black people are wild and that white people are elegant, are no longer removable. However, I hope that you will admit each other's features and make them laughed by their jokes.
