Steve, I reject several of your premises.
First, racism is judging a person and assigning characteristics solely based on race. It it appears your stance is blacks can’t be racist because of an assumed “power” difference. That is simply untrue using my definition. Of course you prefer your definition so we will just disagree.
Second, you assume ability to frame the issue. That sounds very powerful. Are you being racist? You have met at least one of your requirements, no?
Third, I honestly have zero idea what your last paragraph means. I read it. I tried making sense of it using some assumptions. If it is important to you please try again.
Fourth, I will read the first 11 pages you recommended.
Last, every person CAN be racist. It is dumb and lazy. Those two inputs rarely benefit the owner of those qualities.
