However, we should. Because of different skin colours, they have something in their mind that they may not be able to understand each other. Therefore, if they can understand each other as they do with same skin color, the possiblity not to have a discremination will be born. I think that it is noy only problem between black and white. Even if people are the same races, I think there is a still discrimination among those people.
Many people still have the stereotype about the different ethnic group.
Japanese people treated many Asian people badly. Especially, from Meiji era Japanese treated Chinese people and Korean people cruelly. During World War Two, Japanese treated a lot of people in many Asian countries and killed them without any reasons. Japan treated Korea as a colony of Japan, and robbed the right to live. During war, there were many stupid projects by Japanese army and used a lot of Asian people to support Japan and killed them.
