I do not agree, see no evidence for your claim, and consider it laughable at face value.
As a white dude, I have never gotten the impression that because of my white skin, BAC considers me and my race to be inferior to his race. Which, by definition, is what constitutes racism.
I also think the fact that only Trump boot-lickers call BAC racist should call into question the motivation and plausibility of claims about his alleged racism.
What it comes down to, IMO, is that Trump boot lickers do not like "uppity" black posters providing their perspective on America's long and sordid history of racial politics and racial identity.
