At this point ‘racist’ is basically just an ethnic slur for white people.

I feel like white people should just own it. Make it their word, that only they can say. Meet another white person, “Hey what's up my racist?” “Nothin much racist, what's up with you?”

Anyone else uses it in your presence, just chimp. “Yo wtf did you just call me?”

Actually I feel like this is already low key happening. White libs already established the frame that all whites and only whites are racists, and they spend their time wallowing in that. On the right, you've got the esoteric circle of dissident anons who openly identify as racists without being bothered by this, and then you've got the exoteric circle of conservatives who rail against critical race theory in the schools and get performatively outraged by any and all accusations of racism against their person.

So the elements are all there.

Come back in a decade and only white people will be allowed to use the r-word.
