I think we just realized how overly clinical and dehumanizing it is and it just became an easy tell that that person probably, whether they realize it or not, doesn't really see women as equally human to men, like women are only the sex characteristics that make them biologically female.

To be clear, im referring to the phenomenon where someone, despite frequently using the word 'men', is seemingly only able to refer to women as 'females'. You almost never see 'males' used in that standalone way outside of clinical contexts. So yeah, blame those people for ruining it, not the rest of us for wising up to it.
