Look you don't have to be dysphoric about your entire gender to be dysphoric about specific body parts. People should be able to get top surgery or a hysterectomy or whatever, on demand. For whatever reason.
Getting rid of my uterus was one of my first experiences of gender euphoria, before I knew what nonbinary was.
I asked for a breast reduction, they refused on the grounds that it was cosmetic, that my breasts weren't large enough to require a medical reduction. I boggled at that, and then said, "Fine, I'm nonbinary, we'll go the gender confirmation route."
And that got the process done. I am nonbinary, but it shouldn't have taken that to get 22 fucking pounds of breast tissue removed. How goddamn large did they have to be to justify a medical reduction? My O2 sats went up after the surgery despite the post surgical binder. I medically needed them gone. I could not medically get them gone, but could do it as gender affirming care.
Someone close to me would benefit from a hysterectomy, wants a hysterectomy, and was told that her excruciating pain and excessive bleeding and exhaustion and lack of interest in future procreation was not sufficient to get a hysterectomy paid for by medicaid, but when that person said, "I'm genderfluid and I want gender affirming care" suddenly everything was covered.
And I 100% support that, even though it didn't even occur to her to think of herself as anything but female until I suggested it, but on thinking about it she decided genderfluid worked for her.
But even as a nonbinary person, I am DEEPLY disturbed that the easiest way to get essential care is to stop being female. What the everlasting fuck. Just give women hysterectomies if they want them. Same as you do for vasectomies. Someone wants smaller tits or no tits? De-vavavoom them.
And if you have to ask for gender affirming care in order to get necessary medical treatment? Go forth with my blessing.
