I think ideologically it’s all based in some sort of weird ‘transhuman’ belief that we can somehow transcend our bodies.
Bodies are just customisable accessories to our (innately gendered) souls - so we should be able to modify and tinker them as we see fit.
Funnily enough, pesky biology is both more complex than that and more important to our lives as corporeal creatures than ideologues want to believe.
The medical-pharmaceutical industry is not a place where ethics seem to matter as you think it should either. Encouraging the belief that all of this stuff (a) actually works to achieve the ends people desire and (b) is otherwise innocuous seems to be pretty standard practice in that sector (especially in North America).
I read Empire of Pain and Dopesick last year, and some of the same problems clearly drive this desire to present hormones and surgery as lovely, benevolent, and utterly positive in any way. Different drugs/treatments, different populations but similar levels of dishonesty. Made worse because the media (mainstream and social) are so much more keen to position access to ‘all the surgery’ etc as a basic human right for the most vulnerable people on earth.
Ironically without considering that one of the principle things they are vulnerable to is unscrupulous practices in the medical-pharmaceutical industry.
