Dr. Mark Goulston, White co-host of the urban Black "Zo What Morning Radio Show," explains that racism against Black males is often caused by White males and even Black females projecting onto a Black male the belief that he must be angry.
That is because if a White male or Black female were treated the way Black males are treated by being dismissed, looked down upon, jumped to conclusions about, that White male or Black female would feel angry. And therefore, believing that, White males and Black females are always looking for that anger and when it is not expressed, they believe the Black male is feeling it, but holding back.
Feeling and believing this makes Whites and Black females feel justified in preemptively attacking that Black male as a way of the Whites and Black females protecting themselves. In other words their aggression towards Black males is based on fear.
Furthermore, Dr. Goulston believes that until Whites and Black females realize they are doing this, take back their projections and listen openly to the actual words and behavior they are hearing and seeing, that fearful aggression will continue as well as the resultant aggressive and racist behavior.
