He/him lesbians are a historically present thing from back when gay people couldn't be openly gay, and looking like a "man" helped keep oneself and ones' partner out of trouble. AFAIK it's pretty much exclusively for butch lesbians, was popularized by the author of Stone Butch Blues (book about being a butch woman), and
was completely disconnected from troonery. They lived as women, identified as women, and didn't think they were rEaL mEn. The only people I see use it today are butch women and troons LARPing as butch women, and both (IMO) are autistic for using it in current year, especially with troon shit going on.
Kev, on the other hand, is on some asinine, high tier autism with the bi lesbian shit, part of which seems to come from bi women upset they aren't lesbians and desperately clinging to the label for woke points. Most of them claim to be mostly into women (or "woMeN aLiGneD FoLx") but, especially with how many troons use it. I'd bet money it's the pseudobisexual AGP kicking in - you can see it in Kev's response of not being into dudes but constantly jerking off (metaphorically, of course) to the idea of dudes fucking him. The confusion of arousal at the idea of them being fucked by a dude and the arousal they get from women because they're straight men likely leads to the utterly retarded argument that anyone can be bi and gay, or bi and straight, or straight and gay (yes, bi lesbian discourse has finally circled around to "straight lesbians").
Long post is long, rate me MOTI but this shit gets under my skin. Men LARPing as women redefining what women are and what lesbians are, and then turning around and having the gall to whinge about gatekeeping in the community is the most ass backwards shit I've ever seen. Disagreement of any kind is not allowed, though, how could I forget
