I am speaking specifically to your statement:
Why would they do that? Just because black people are over here being carefree and worrying about themselves? That is not how it works. Throughout history black people have been minded their own business and worrying about themselves and their self worth and you know what happened. Black wall street, the bombing in Philly, bombing of churches, Rosewood, ect...
You are right black people should have the right to be carefree, peaceful and angry but that is not reality. That is not the real world. People are mad at black people being mad about this. Even now times are changing, white people don't even worry about being "politically correct" any more. Since Obama ran for the first presidency there has been blatant disrespect, blatant line stepping. Being Black in America it would be a disservice to yourself to be carefree you are in a hostile environment.
