I don't like Trump but I still agree that racist is now used as a general slur.
"it seems like you are missing the point: in a pervasivly racist society, discriminatory behaviors creep in the subconscious of everyone, black/white/antiracist/whatever, and we have to consciously struggle with them."

We all hold prejudices that we all need to be mindful of. Getting tangled in the weeds of arguing about semantics completely derails that point.
Racism is the discriminatory or prejudicial treatment of people based on these socially-salient-but-mostly-arbitrary social categories. This is pretty basic stuff, really.
