I’ve been hollering that gender is grammatical, and equating it with birth sex (as opposed to the act) is purely Newspeak, from Orwell’s 1984. When did people start using gender to refer to anatomical sex?
Gender is grammatical but there are quite a few areas that are defined, if not you birth sex, at least by their prevalence among males or females. Some of these have been greatly diminished by females becoming more prevalent in male gender areas. Occupations, clothing, interests and recreational activities have seen a somewhat diminished male dominance. The reverse, save for an infinitesimal few has not been true. 60 years ago when I graduated 8th grade from a NYC Catholic School we had a Gestetner printed yearbook. Under our names each kid stated their occupational goal. With one notable exception the girls, even the brightest, chose feminine positions, teacher, nurse, secretary. One girl chose lawyer and the nuns tried to have her change. It wasn’t proper. None of the guys chose a feminine gender job, even though I eventually became a teacher. I suspect a yearbook today would look very different for the girls but hardly changed for the guys.
