When people talk about the disposability of transfeminine people it isn't just about the sharpest examples where someone is pointedly ostracised. Straight trans women know that lots of men don't want to admit they're with a trans woman, trans lesbians far more rarely express the same with cis partners. Many cis lesbians will date trans women and a subset of them are absolutely ride or die but the ones who aren't can be just as bad as cis men about this. Generally though, it's a subtler thing. I know trans women who have been parts of their respective friend groups of mostly cis people for years and years and been passed by as people just happen to form closer friendships with each other, with other transmisogyny exempt people, cis lesbians happy to date trans men but not trans women, events that include everyone but the transfems, spaces that exclude trans women or make us unsafe used for community spaces unthinkingly, and bit by bit the only trans woman in the friend group lags behind.
The "uninterrogated ick" is what I often think of this stuff as. Society teaches a level of disgust to everyone about certain groups of people in some different and some overlapping ways. For example people of colour, especially black people, experience forms of racism associated with a presumed uncleanliness. Homeless people, sex workers, queer people, "criminals", all these groups are stigmatised as unclean by the mainstream implicit biases spread unconsciously (and sometimes very consciously) in culture.
Trans women who have experienced harassment and ostracism campaigns experience a more intense form of the "uninterrogated ick". It is literally exactly all the same forces that ostracise trans women from society in general but dialled up to the nth degree. The Bad Tranny is unemployable, finds it harder to get housing, is fun to fuck but too risky to introduce to friends, and should be excluded any time someone feels uncomfortable. This is why trans women feel unsafe in spaces that spread callout posts, for the record, if anyone unaffected by transmisogyny needed that unpacking. The push and pull of this "ick" affects all transfeminine people, and the division between the good tranny and bad tranny is illusory - we can see this in how many stated reasons for ostracisms boil down to "she icked someone out and then was declared bad and ever since then when she shows up somewhere the ick is worse which is a crime against the people there".
Transgender woman: you deserve partners who are excited to introduce you to their friends. You deserve friends who are excited to introduce you to their friends. You deserve organising comrades, colleagues, community members who will check in on you, recognise your vulnerability and give you the space to just be. You deserve people in your life who proactively include you, not people who frown a little and shake their head when you're pushed out and certainly not people who resist helping you build up community and support around you. You deserve everything, do not accept less.
