“Racist” has become a left-wing synonym for “conservative” or “Republican”.
Since they usually think those of darker hue aren’t smart enough to compete on a level playing field (racial preferences), I guess you can play by their rules and call them “bigot” right back, with more accuracy.
Of course the BLM set will look right at you and say that “black racism” is impossible. They are Too Oppressed For That To Be The Case.
