The 1970s and 80s would beg to differ! Please do an image search for Marilyn Peter Robinson of 70s/80s fame. There were tons of guys like that back then, and tons of women with crew cuts and shaved heads. None of us pretended people could change sex or that we had discovered some new "gender wisdom" that previous generations had been too dim to figure out. Because back then queer theory gender ideology was not yet a thing. Transsexualism and so-called "sex change" operations were well-known, and much discussed - and there were a whole lot of gay male transvestites and straight male cross-dressers, just as there had always been. But no one spoke about being "born in the wrong body," or claimed that everyone has an innate "inner gender essence" and needs to discover and declare their "gender identity" like today because such malarkey and slogans had not yet been thought up yet.

Today, Marilyn from back then - who goes by Mr Marilyn - "presents" very differently, as most people do as we age. Over time, experimenting with fashion and being outré and edgy loses its appeal, and people move on to other things. Mr Marilyn is now considered a transphobe for tweeting, "there are two sexes. End of" and for not wanting his elderly mum to have to share a hospital ward with a man who IDs a woman, or to be forced to get intimate care from a male who likes to "present" as Mr Marilyn did in his own youth.
