For as rare as transgenderism was among boys/men, before the current social forces were in effect transgenderism was all but unknown in women.

I'm not quite sure that's true. There's a long history of mental illness. Pauli Murray was a prominent and famous one that leftists love. Or the "Universal Public Friend" what the fuck that is about.

Beyond that, there's the "Lesbian Extinction Theory" -- all the Lesbians (especially the butches, the bulldykes, etc) are turning into men, so the only "lesbians" left will be the men who play dress up.

What a fucked up world we live in.
