This isn't the first time I've seen FTMs afraid of being in male spaces - it's like deep down they realize they are women and men are men, and are still afraid of men, and can't help but express that, but if you press them for details, they'll never say exactly why they're afraid, because it would mean admitting they they're women.
Which is exactly why they make such great victims. Transmen are constantly being targeted by MtF predators who know that this type of victim will have a hard time admitting they're being abused in the exact same way male abusers always abuse their female partners, because if they admit that it might destroy the illusion that they're a genuine manly bro-dude.
I know this has been said a million times but I just cannot get over how goddamn female Aidens are. There are so many writers who don't have a particular male or female writing style (this varies across genres, obviously) and yet every paragraph written by every Aiden screams female so loud it might as well be written in sparkly pink gel pen on unicorn stationery.
Look at those two women in the AO3 comments examining their feelings together! And examining the feelings of story characters. And making sure to flatter the feelings of males who aren't even in the conversation by asserting to each other that of course they support transwomen in women's bathrooms. (Even though males are dangerous to women, which is why transmen are not safe in male bathrooms...)
How many times do you see transwomen studiously reminding each other mid-conversation that transmen have needs too and must not be excluded from consideration? Fucking lol.
