the term "biological sex" doesnt make much sense tho

what are all of those complex medical treatments trans people can get, if not biology? far more advanced and interesting biology at that

and "biological sex" isnt a binary either, 1 in 40 people are intersex, mostly with almost no effect, but not in the binary either

Yes, and the language for that is "biological sex." If you go to the doctor, they will ask you for your biological sex.

"Biological sex" is poor language because it doesn't actually provide any useful information. It says nothing about my hormone levels, it says nothing about my fat distribution, it says nothing about my (in)ability to have kids, it says nothing about my dose requirements, it says nothing about my genitals, it says nothing about my medical history, it says nothing about my BMI, it masks certain cancer risks, it has never actually achieved anything useful at the doctor's office. All it does is placate transphobes and cause bureaucratic headaches.

If a medical form needs to know if I can get pregnant, the correct language is "are you able to get pregnant". It's not transphobic to ask that in a medical context, if anything it's expected. It is transphobic to assume a trans person can't answer that truthfully. Besides, the question also covers cis women who can't get pregnant and trans men who can.

Doctors don't immediately get amnesia when something gets defunded ... But claiming that doctors suddenly don't know what to do is a hyperbole that misses the actual issue.

Yes, they literally do seemingly get amnesia. One of the main complaints we have about doctors is that they dismiss every concern by blaming it on us being trans. I've heard it described as "trans broken leg syndrome". It's a similar issue to what cis women face, almost like it's a systematic issue that affects anyone who isn't a cis man.

That should all be taken into account, of course, but pretending that "biological sex" is useless in medical contexts is an ignorant take.

This is contradictory. Trans people already face discrimination and confusion from doctors on the norm. Eg: I've even had issues with my ophthalmologist, as if being trans has any effect whatsoever on my eyes. A single binary "biological sex" marker erases all the nuance involved and strips us of the language needed to properly convey it.

And besides, if "biological sex" is such a bogus concept, then what do we even contrast "gender" with in the first place?

Individual physical characteristics. Call it "Sex" and leave it open ended for all I care. It's the enforcement of a strict binary, removal of agency, and purposeful ignorance of modern science that I take issue with - all while hiding under the term "biological". It is for those reasons that it is often used as a dogwhistle.

Finally, your persistent sealioning only contributes to the problem that no one ever fucking listens to trans people. We are a tiny and very vulnerable minority who are constantly being drowned out in a sea of cis voices that think they know the trans experience better than us (eg: when was the last time you saw NYT quote a trans person?) You have easily typed out more than any trans person in the conversation but have seemingly learned absolutely nothing from it.

You are sealioning. You don't speak to your doctor in order to use the loos. In this context, "biological sex" is a transphobic dog whistle.

Just FYI, I've never been asked about my "biological sex" from a doctor, and I'm pretty sure you haven't either. You've been asked about your sex. That's it. "Biological sex" is a right-wing dog whistle.
