a lot of trans women start out as amab socially awkward nerdy white twinks, they usually don't have too much luck with girls if they are attracted to women, also they are very often excluded from developing like the rest of the cis girls even if they are very feminine and passing, missing key formative experiences of femininity. Most trans women also lean left politically for obvious reasons, this results in often trans women being dedicated feminists, and here within lies the issue, because trans women are outside cis femininity, they don't understand that cis women, especially cis het white women from the 2nd wave of feminism have spent decades crafting a very particular idea of "feminism" and "equality" that revolves around aesthetic and vibes, while the material reality differs much so and women still fill all the "traditional" feminine roles.

As trans women continue to actually strive for equality, they will continue to be excel in their fields of choice as they do now, where you see so many of the mathematicians, programmers, biologists etc are turning out to be trans women in fields typically dominated by men, obviously this will fuel transphobic rhetoric, if cis women don't go along with this and other trans women and say they are actually men, then they will be humiliated by this reality that these women they don't even consider to be women are dragging them kicking and screaming into equality and making them actually have to live up to standards they never wanted to, and exposing the crux of the matter, that women really really regret feminism because they actually have had it pretty good, better than basically any group, even cis het men who are more privileged than women in the societal constructs men have created can never match the existential necessity of cis women, certainty better than the nightmare existence of trans women, a group of people barely humanized to be considered a sexual fetish, a tiny minority that could be wiped out if society willed it at any second, that serves no material purpose to it outside of said sexual commodity.

In this cold heartless world of no guarantee, everyone is disposable except (cis) women, because they can give birth and are necessary for civilization, nothing can touch this privilege, this guarantee of necessity that transcends societal and culture bounds to be an existential need, the reality has always been that women are the world, and there only needs to be one man in it for all of society to flourish, but vice versa would never work, yet women viewed that transcendental position of power as chains, and now are realizing what a mistake they made, and the humiliation burns because if they fail, then it's true, there is nothing that "men" in their minds can't do better than them, including being women, and not because biological determinism or anything like that, simply because they didn't have the willpower transwomen
