We get too hung up on language, IMO. For example, calling someone “unhoused” vs “homeless” does nothing to put a roof over someone’s head. Whether we capitalize Black or not does nothing to undo systemic racism. “Latinx” doesn’t make anyone less sexist, or create more opportunities for women. And so on. It seems we’d all rather have good feelings about our word choices than actually solve any problems. Just my 2¢.

i think there are different categories of this. some (not necessarily in your examples) are chipping away at a hierarchy or reducing microaggressions and some are just liberals doing nothing.

also Black vs black is like a culture vs skin color thing sometimes idk if always (also maybe that edges onto that FBA or ADOS shit that none of my mentors like) My understanding is the capitalization is for when you're referring to the new-world cultural group that was developed by enslaved black people, but maybe that distinction isn't valuable to everyone.
