Your approach leads to individualist reductionism. It refuses to engage with the systemic factors at play and instead vaguely gestures at a hollowed-out, meaningless definition of “transmisogyny for everybody” that obfuscates the root causes of transmisogynist opression and eradicates those most affected by it from the discourse by equating us with a cis guy who has decided to wear a skirt today. Sorry for being so direct, but i have no patience to mince words about my erasure.
Firstly, yes, cis women, GNC men and transmasc nonbinary people can also be targeted by “misdirected” transmisogyny (a problematic term in my opinion, as it implies that transmisogyny hitting me is aimed at the correct target). However, attacking a cis woman or other TME person by insinuating they are transfeminine only works because trans women exist as a hypermarginalized group that is ok to bully, harass and attack in any way people please. Claiming that a person is secretly a trans woman is marking her as a target for transmisogynists. It would not work if trans women in themselves were not subject to a particularly vile and unique form of discrimination.
Secondly, TME people as a group are frequently better protected than TMA people. This frequently gives them better legal recourse in a structurally transphobic justice system, it will make a lot of people wave away the attacks against them as ridiculous, it also usually means they have a more robust support network and a better material position. No, not every TME person has better ressources than any trans woman, but the disproportionate economic marginalization of trans women is a sad statistical fact, the gender pay gap affects us even more than cis women, we are much more likely to be homeless, are more likely to be isolated from our families, to have lost friends and so on and so forth.
The latter point is were your “we have to judge this on a purely indicidual basis” approach betrays its liberalism: You refuse to recognize transfeminized people as a class. In your approach, nothing means anything and the only thing you gain from it is not making trans men and transmasc nonbinary people uncomfortable when they lack the ability to reckon their relative privilege. I have written several paragraphs about the relativity of that privilege and it is somehow still not enough for you.
Edit: Also yes, telling GNC trans women they are TME would indeed be absurd, which is why literally nobody is doing that.
Yeah, this is my main criticism with that passage from Whipping Girl: I have also experienced that kind of sentiment over and over again, and it always came from TME trans people, i have never seen that behavior from nonbinary transfems and i have not once seen it directed at binary trans men. In the cases were that kind of discourse pops up in trans spaces, it’s always transmasc enbies attacking trans women. So i wouldn’t call it “binary-phobia”, i do disagree with that wording. It’s just transmisogyny. But yes, it does happen. That does not mean exorsexism and truscum shit isn’t a problem, but i haven’t seen any of that anywhere in Whipping Girl, in spite of the text being 20 years old.
Moreover, this line of thinking is a lot more common among cis people. That’s not to say that cis people aren’t crushingly exorsexist, because they are, but they will shamelessly use the existence of “third genders” in other cultures to tell trans women we are problematic and conservative for medically transitioning or for claiming womanhood instead of allowing ourselves to be relegated to a third gender so that cissies can keep treating us as not-women. Whipping Girl in fact has an entire chapter about that, and keeps bringing up examples of cis people appropriating and weaponizing cherrypicked nonbinary experiences against trans women as “evidence” why nobody should medically transition. It’s a standard tactic of terfs to tell trans women we are “reinforcing restrictive views of femininity” by claiming binary womanhood. And yes, ofc they will immediately do a 180 as soon as they are confronted with actual nonbinary people, but that’s terfs for ya, they have no actual convictions.
