Really pissed me off. Completely ignores the world these women were living in.
Ex-fucking-actly.
Go look at the AO3 fanfics for "The Goblin Emperor", I dare you.
That's a fantasy book that has as its premise a very patriarchal world. There's a female character introduced who wants to get into a job that has previously only been open to males, and the guy who supports her (because he needs to present a suitable candidate for the job and she's the only he can get) tries to pass her off as male. Which his boss immediately sees through (because she's small and thin and doesn't look like a male at all) but still accepts her because he, too, urgently needs someone to do the job.
So, this all established, people still, without reflecting on it, write fics in which a canon male character is secretly trans and got that very same job with no problem whatsoever. Because in a world where women clearly, explicitly have to pretend to be male to get the top jobs, genderfeelz will be totes separate from that and only be had for noble and pure reasons of gender identity, nothing to do with material gain. And only those noble TrueTransmen(TM) will be able to pass undetected.Because they are morally superior to those lowly ciswomen who schemingly, evilly pretend to be a valuable male, and their true male self shines through their lowly female bodies. Or something. (No, admittedly, I haven't read the fic, I didn't feel able to deal with the stupid, but it is fucking insulting, even if it is admitted that the transman looking butchier than the woman-with-ambition is mere coincidence.)
They are shown the world those women live in, and still decide that what this world needs is a woman who has male genderfeelz, and just happens to look butchy enough to have no one contradict her genderfeelz.
( It is telling they didn't take the female character that couldn't pass as male and give her male genderfeelz. Then at least they'd be forced to acknowledge that her worst enemy aren't those evil radfems who don't believe in her gender identity, but the men who don't want to give her jobs)
