Yall have got to be more normal about non-binary people, transfeminism is for non-binary transfems just as much as it is for binary trans women. Transmisogyny doesn't care about the identity of the people it targets, it cares about their assigned sex and their directional movement inside the masculine-feminine hierarchy.
A non-binary person who assigned male at birth is TMA regardless of how exactly the identify, because transmisogyny does not let us be non-binary on our own terms. We're pressured to just be effeminate men, to be femboys, who notably, are a porn category, while prevented from just existing in a space of non-binary identity and presentation that we get to define. (while some transfems do identify as femboys, the fact that the identity is so closely tied to sexualization and fetishization of transfeminine bodies is a product of transmisogyny) Even in queer spaces, we exist inside a conception of androgyny which was crafted by and for transmasculine non-binary people, a conception which does not serve us.
Even the most masculine non-binary person who was assigned male at birth that you can think of, a person who probably doesn't even use the word transfem to describe themselves, is still transfeminized. (transfem is not an identity, remember?) They cannot escape that social process of transfeminization by presenting masculine, in the same way and for many of the same reasons why eggs or non-passing trans girls cannot escape that social process by attempting to present masculine.
A trans girl who doesn't pass still experiences misogyny because, despite the people around her explicitly not recognizing her gender, they implicitly recognize her social class. She gets read as bitchy and needy and loud, like passing trans woman and cis women are, and is faced with the same contradictory standards as passing trans and cis women are.
This doesn't fundamentally change when the transfem in question is non-binary. They may not seek to pass as a woman, but their behaviour and presentation are still subject to feminization, something which carries additional injury when they do not seek to be feminine. They are trying to occupy a social space which does not yet exist, their desired relationship with androgyny, masculinity, and femininity is completely unrecognized, even in queer spaces. Just like how transmisogyny pressures all transfems to just be cis effeminate men, it pressures them as well. Just like how transmisogyny makes all transfems at once hyperfeminine (focus on us doing things like makeup and clothing) and hypermasculine (focus on our masculine features like genitalia and jaw), it hyperfeminizes and hypermasculinzes them as well. Just like how transmisogyny fetishizes all transfem's bodies, it fetishizes their body as well. The social processes at work do not change, only the identity of the target.
This transmisogyny can impact them differently, of course. A feminine transfem and a masculine transfem will react differently to hyperfeminization, for example. The lived experiences of transfems as it relates to transmisogyny are not homogeneous because the identities and social realities of transfems are highly diverse. This does not weaken the analytical power of transmisogyny, because the social processes of transmisogyny remain exactly the same. On the contrary, it means we can analyze transmisogyny from multiple identities and see how the same social force and processes impact different people differently.
Because of their identity, some non-binary transfems will be more affected by different aspects of transmisogyny, and less affected by others, relative to a binary transfem. All transfeminized people (holding other aspects like race and position to imperialism steady, obviously) occupy the same social position, they are simply differentially affected by that social positioning. If a particular transfem is affected less by transmisogyny by virtue of her identity, that does not mean she is any less transfeminized than a transfem for whom transmisogynistic social processes effect very strongly.
Every identity of person does not get their own oppression. Social processes function without regard to identity, this is why transmisandry is a load of anti-feminist garbage and exorsexism fundamentally flawed. This is also why all non-binary people who assigned male at birth are TMA. Their identity and presentation are not irrelevant to the conversation, but they are also not the determining factors in their social class. I feel like I have to point this out over and over because I keep seeing transfeminists play this identity game and by virtue, excluding non-binary people from transfeminism, and frankly I'm sick of it.
