Racism is the belief the superiority of a particular race, and it’s the theory that human abilities are determined by race not by the content of their character.
Reasons of the existence of racism are: immigration because many people immigrate to seek a better life but the host inhabitants think their country has become populated and dirty,
the whites' feeling of superiority white people are given important jobs whereas immigrants are limited to unskilled jobs with low pay, the competition with the white population economically the whites are worried about the success that blacks have achieved in sport, business, commerce…. Prejudice and discriminate mainly due physical differences the blacks are rejected because of their skin colour or eye shape. They are also rejected due to their social origins.
