Make your pronouns "jewish/black/white/immigrant/muslim/communist/christian/homosexual/transgender/provaxx scum". Make them say it. Any one of those. They'll self censor or hilarity will ensue and they'll piss off or enlighten some major group. Be deadly serious about your pronoun, and completely "woke" about it in every other way. If need be you can improvise some woke-splanation about how its to "raise awareness about xyz by being anti-rightwing and subversive." And then call them a poser and a fascist/nazi/antisemite/homophobe/misogynist/etc if they disagree.
