Racism in sport

Racism is a persecution of people who have other skin colour. This phenomenon has started at the turn of the XVth and XVIth century while many people started travelling to other countries and trading slaves.
Mostly marchants were while people and they bought people who have other skin. Slaves usually worked hard on the plantations. When they were in bool condition, their lord sold them to other merchant. Now, we also see that situation. White people discriminate people who have other skin. The same situation is in sport, but now people are more tolerant. We accustomed to view of black or yellow people on our TV screens.
There are sports which I don?t immagin myself without for example black people. One of those competitions is undoubtedly basketball. The biggest stars in basketball are black players. Just they can make big sport show. A lot of fans have football and in his sport we have the biggest racism. All the time, we hear about racism in this sport. In every match in Europe, fans of the rival team are chanting. Very vulgar shouts advessed to people with other skin. Now, it is changing, because international sport organizations declare war to overcome that situation within a year. We have at least few dozen of years to exterminate it.
It is unnecessary because we are all people and everybody vants to live narmally. I think that white people discriminote other people in sport because they have better form and technique in many sport disciplines and white people are simply jealons of that. I think that white people should be more tolerant to other people, because unless we persecute other races we will not hear about racism in future.
