One thing I do know is a black man can be dressed to impress, dressed as a businessman or other positive, speak affluent and etc. in a fashion that a white man can be seen in the same but I have heard of many incidents where the black man was treated as less human just because.
I am not going to get into a debate over who is the most racist but when folk do debate the issue, I ask that you make sure that the debate includes the status of the person carrying out the racist act. Actually I have not met a racist black man or know of one.
A black man being abused by a white man in authority be it law enforcement, supervisory role and other titles speaks volume.
A white man being challenged by a black man because of the racism displayed can not be compared to a white man in authority that use his power to carry out his mission.
