What I see is an ever-shifting goalpost of harmless aphorisms that are newly considered 'offensive' by a bunch of upper-class people. What does that do for George Floyd's family, exactly? Did it prevent Jacob Blake from being shot in the back a few months later?
If you want to embrace critical theory, you should include the critical theorists in the analysis -- what's their power incentive? What do they stand to gain? Let's not just assume they're saints but everyone else needs an inquisition.
Maybe people are objecting to a tiny % of critical theorists trying to seize control of acceptable language with no mandate.
