It’s like a woke cycle. I’m not sure it’s really about the words, but in some ways, the new people look at the terrible attitudes of the previous people (easy to count on that) and feel the need to disavow it by creating a linguistic line in the sand.. some jump over it, but the others get the sharp end of the stick, culturally speaking.
The advocacy and social signaling feels more imperative than the ancillary social improvements that may be happening either way. It also feels generationally alienating, while some of the “I see things with new eyes” part can happen even among those who don’t even know the words have changed.
