Bathrooms and changing rooms determine most of access to society.

Male people have never been denied toilets, change rooms, clubs, education, sports, the right to vote or anything else limiting their "access to society" based on their sex. Only female people have been. If some males don't want to share toilets and change rooms with others of your sex, then campaign for additional options for you. Stop invading and trying to take over girls and women's spaces.

Define recently. Bottom surgery itself in 90 years old. And if you include non-binary identities like the Hijra literally thousands of years.

By recently I mean since the mid-1970s - so a bit under 50 years, though the trans assault on women's rights has only gotten ferocious and gone mainstream over the past 20 years.

I don't think any surgeries done on "male to female transsexuals" 90 years ago are analogous to what's called "bottom surgery" today. The modern method of penile inversion to create a pelvic cavity was pioneered by Georges Burou in the late 1950s. However, male castration has been around for thousands of years.

As for the Hijra in India/South Asia - this and other similar categories in other cultures are special sex castes created for gay men to separate them from other men. Hijra have nothing to do with women.

putting trans women in men’s prison is basically guaranteeing they will be raped.

Male-on-male violence is for males to sort out amongst yourselves. Putting males who identify as trans into women's prisons doesn't just guarantee that women will be raped, it guarantees that women will be locked in with males who will menace, intimidate, bully, perv on and otherwise abuse them - and some women will become pregnant as a result.

Most males who identify as trans are sexually attracted to women. The ones who end up in prison have very high rates of sexual offending against women and children. In the UK, statistics released by the Ministry of Justice in 2020 show that more than 58% of the males who identify as trans incarcerated in prison in England and Wales in 2019 had at least one conviction for a criminal sex offense. This compares to 17% of the male prison population overall, and 3% of the female prison population.

Even homosexual males who identify as trans are often misogynistic and full of rage towards women, and since they have male bodies and assets like male grip strength, upper body size and hand size, they can easily overpower females. These same features also give homosexual males a fighting chance to defend themselves if/when physically assaulted by another male. Women don't have that same fighting chance.

Also, trans-identified males are not the only ones who are vulnerable to physical and sexual assault by other males in prison. If this one group of guys should be put in with the women, why not all males who are skinny, frail, weak, good-looking, very young, old, sickly, physically disabled, mentally slow, traumatized, mentally ill and so on? Why not all the males who are child molesters or serving time for collecting images of children being sexually abused by other men? After all, "nonces" are at great risk of assault and rape by other males in prison too.

Finally, not all incarcerated homosexual males who today would fall under the "trans" umbrella are champing at the bit to be placed in women's prisons. Many prefer male facilities because in men's prisons they have a chance to have male-on-male sex and intimacy, to keep the dream of "meeting a guy" and falling in love with him alive, and to hook up IRL with another guy who will care for and protect them. In male prisons, these males often are valued for their ability to give blow jobs, their willingness to playact "in the female role" in penetrative penile anal sex, and their ability to smuggle contraband into and around the premises by stuffing it far up their bums. In women's prisons, these inmates aren't anywhere near as highly valued - and there's zero demand for their blow jobs, for them to be bottoms in anal-penile sex, or for their skills in using their anuses for smuggling.

Health care determines whether we live or die and “trans broken arm syndrome” is very real.

Women's health care needs have been ignored since medicine began. A lot more money and resources have been and are being put into "trans health care" than into areas like endometriosis, pregnancy complications, high maternal mortality, childbirth injuries, menopause and the health problems of elderly women. Now gynecologists are being expected to provide health care and prescribe and monitor the pharmaceutical hormones of trans-identified persons of both sexes. Males who identify as trans are also demanding that gynecologists - most of whom are female - provide them with care following genital surgeries, and prostate exams too - tasks that are in the wheelhouse of urologists and andrologists, and for which those sorts of specialists are specifically trained. This is diverting time, attention, resources and knowledge from female-specific health care and giving it to male and female trans people whose health care is experimental and who have health care problems that are of their own choosing, and which gynecologists are not trained to handle. It's also turning gynecology away from female-specific health care to males with male-specific health care issues. How is this just?

Lots of people have trouble accessing medical care for all sorts of reasons, and have our symptoms and problems ignored or pooh-poohed. Trans people have no idea what it's like to trying to obtain medical care for persons who have a rare or "orphan disease," or several rare and poorly-misunderstood medical conditions at once.
