What do you call a non violent black person? Mixed race.
What are you trying to say about black people with this joke?
The only way a black person isn't violent is if they're mixed with another race!
When people assuming that all black people are violent it dehumanizes them and encourages people to be racist toward them. Black people are no more likely to be violent than anyone of any other race. You should try to be more sympathetic to other people.
