Warning contains a rasist word

Why do black people in YouTube and vine videos say n**ga a lot no joke look up the King nappe or the watermelon guy and most of the videos have n***ga
In it but the problem is that if a white person says the word blacks have a go at you and say that's racist and all that but they say the word so why can't white people without offending a black person but why is it that black people can say the word but white people can't
Ok rant over
