Almost everyone who opposes trans people's existence today. Opposition to trans rights is rooted in patriarchal hegemony and the control of bodies. Our existence is a fundamental threat to the foundational perspective of the predominant power-structure in society.

No one does a womb-check before granting women validity. It's always been a vibe thing and people who do not conform to the prescribed model of existence as a man or woman are constantly denied full privileges under the framework. It's not just trans women getting the short end of the stick here, it's everyone: men who do not embrace dominance culture or otherwise display "effeminacy" are denied true Man status, women who don't meet beauty standards or possess a submissive demeanor are slurred as bull-dykes or the dreaded transexual.

This isn't an issue with any real reasonable basis for it's opposition, it's a golem of pure hatred and disgust in a suit vs. people who want to live full, free lives.

editing to add: the first known uterine transplant was performed on Lili Elbe who received treatments through the Institute of Sexology in Germany. The Institute was famously destroyed by the Nazi regime. It's barely coincidental that fascism has risen again as medical science brings this technology to maturity. Trans women gave their lives for this medical miracle.

Have you considered that people just think that performing any kind of sex-change operation is dumb, made a deduction from that that the subject is dumb, and everything else you mentioned stems from that?

Much simpler explanation than "power structures", which makes very little sense considering most people don't have any power.
