Treating alt-right radicalization as a thing that "could happen to anyone" or that "gets done to people" (subtext: with no agency on their part) is a short road to treating ex-racists like survivors instead of perpetrators. Don't do that shit.
white people are the worst-placed out of anyone to perceive our own current racism so like others have already said more articulately, calling oneself an ex-racist is sus as fuck to begin with - how would you even know that, if it seemed fine to you before?
@LaComtesseRouge this part always gets me!! like stop pretending as if you have been uniquely prepared by this experience to fight against propaganda. "ex-nazi" is just a way of telling the world that you're extra-susceptible
