In America for a long time ago, the racial discrimination was very obvious. Every day the black were treated very badly by white people. The term "Negro" was applied to people
descended or partly descended from slaves transported from Africa long ago.
Nowadays, the racial discrimination isn’t just between the white and the black. Many other races in the wold are discriminated by the local people and their life are very bad. However they don’t even have any rights to protect
But the fact that more and more proof, in terms of sport meeting , the black are definitely stronger than the white. There are whites, blacks, male, female, rich and poor. However no matter the differences, discrimination is wrong. So as long as we change these wrong perceptions, I believe this world will become a fairer one.
