While I do also want this for transmasc folks as well, and in fact literally any trans person, the reason I made this transfem specific is because transmisogyny is so damn strong. Let me explain:
I saw you tag this as transmisandry; transmisandry does not exist as an intersectional form of oppression because oppression does not work that way. Many folks (i assume yourself included!) view "oppression" as a term for just "hating someone based on who they are", it is not. The word for that is "prejudice". Oppression is actually a coordinated system which creates a dichotomous hierarchy of one group over another, where one group is given privilege (primarily in the form of autonomy and power) while the other has it taken away from them *on that basis*. As such, theres no such thing as a "reverse bigotry", reverse racism does not exist, cisphobia does not exist, and misandry does not exist.
What events often MISTAKEN for misandry are the side-effects of misogyny--Women are treated as emotional, illogical creatures, so to prevent being treated as "lesser" like women are, men often have to hide their feelings, leading to increased suicide rates (not talking about your feelings is a good way to let depression fester). Transmasc folks, especially trans men, also often mistake the transphobia they DO indeed face for misandry. but make no mistake, trans men have it easier in the grand scheme, albeit still not *good*.
This is made clear by the transgender wage gap (Trans men make ten more cents on the dollar than trans women, but both of us make less than any cis folks), as well as the fact that recent laws in the US have specifically targetted trans women. In fact, in the recent supreme court ruling on trans women in sports, they decided not only that trans women cannot participate in sports, but Amy Coney Barrett specifically brought up that this doesnt count as transphobia because they still allow trans men to play. Meaning not only are trans women being specifically targetted more than trans men, but *trans men are being used by the bigots as a way to cover up their bigotry*.
And that, interestingly enough, parallels perfectly the case that Kimberlé Crenshaw used when coining the term "Intersectionality". In that case, a black woman was told she could not claim that she was discriminated against in the workplace because she said that she was being targetted for being a black woman, and the law only recognized bigotry if it was either antiblackness or misogyny, not both. Similarly, trans women are told we do not face bigotry quite often for being trans women, we are granted claims of neither transphobia nor misogyny. This is why intersectional oppression is objectively worse, because you are granted none of the grace of either vector of oppression. Theres no protections, no love. And it only gets worse as you get more intersections, black transfems face transmisogynoir which is far worse than what i face. They have the highest murder rate of any demographic.
And that is why I wrote this about trans girls specifically. Because while trans guys are told they are silly confused girls who need to learn their place (Still horrendous), trans girls are told we are irredeemable perverts, child molestors waiting to happen; if we are angry about our lives we are told we're too masculine and "fake women", if we are too emotional we are told we're hysterical and thrown in mental hospitals.
