Because he is black and therefore has rights as a black person. He is never considered guilty of prejudice against whites. He can call us whitey and no one can sue him.
The whites have no rights, no quotos that have to be filled for jobs, school, etc.
We are still in my opinion paying for our ancestors using them as slaves, which was not right in any form. However, they forget that their nation of origination sold them to us.
Amazingly enough, no one talks about the original settlers and how many of them were endentured slaves paying off a debt to someone that owned their services in England until the debt was paid off.
Nothing should be decided, in my opinion, according to race.
