transphobia, terf psycology
I'm over generalizing and doing some armchair psycho-analyzing here, but I don't think this is a coincidence.With TERF's there's probably a lot of insecurity and projection going on where they themselves have been bullied and invalidated for "looking like a man" for their jaw lines or shoulders or deep voices or any trait that could be singled out for being "manly" but the way they were always able to counter this is "No, I am a woman! I have a pussy and a uterus!" so they hate men for this ( not unreasonable ) and feel they've had to fight to affirm their own gender identity (they have), but because they accept traditionalist genital based definitions of gender and fail to recognize how this is itself a patriarchal construct -- including the implicit biblical concept that to be a women is a curse, and their fate is beyond their control -- the existence of trans-women explodes this entire framework and terrifies them; if trans women are women, the basis of their gender identity evaporates. They falsely see trans women as some conspiracy by "men" to take away the gender identity which they've had to fight for, so ironically the end up siding with misogynistic anti-feminists in the process.
I am probably oversimplifying but if you've spent any time arguing with TERF's it won't be long before these references to school yard bullying come up. Or they'll point to a butch lesbian and be like "See, she's not a trans man, she identifies as a women, trans ideology destroyed" as if anyone was calling that into question. Who is saying she's a man? One gets the impression these TERF's are haunted by their elementary school bullies who point and sing "You're a boy! You're a boy!" all day long. TERF girl huddled into a ball like Asuka in The End of Evangelion: "I'm a girl. I'm a girl. I'm a girl. I'm a girl. I'm a girl. I'm a girl. I'm a girl. I'm a girl. I'm a girl. I"M A GIRL! I"M A GIIRLLL!"
Again, I'm speculating, also extrapolating a bit from my experience as a boy who has an androgynous name and traits that are considered "girly" I understand that trauma, tho my way of coping was more leaning into the "girly" aspects of myself, because bitches love that 😉 ( jk, sheesh) but in the end, even though I've dealt with a lot of gender dysphoria, i'm still cis, I'm not just a man because I have a dick, this is a choice I've made, to be a man because that works best for me. It's liberating to know that you have that choice. TERF's are afraid of freedom, like all fascists.
