Nauticant nails it.
I'll write what I wrote before. This business of uterine transplants into men appears to be about science but it is not. It's about getting the idea out there that men can give birth too, but not just yet, there are a few technical details to be sorted out first. So while we're waiting for the inevitable, let's get on with the social sciences side of things and accept that since men can give birth too (not yet, but soon, soon, it's bound to happen), then there are no real differences between men and women in terms of things that are material and significant. The only differences are simply surface ones like the chosen forms of appearance.
It is about trying to change how people think by assuming a medical horror is a run-of-the-mill thing just round the corner. It's Overton Window stuff, not science.
I came across wombtransplantuk last year. My first instinct was: it's a front.
Spend a minimal amount of time pretending this is a service for women, then segue into the real reason, wombs for men.
Not because this will ever be more than a Frankenstein experiment. But because there is money to be made, and laws, policies to be changed.
Make people think it's possible. Change ethics rules. Erase the distinctions between the sexes further, on paper. Blur the lines that distinguish women's health, and women's rights. Change the priority order of the most deserving. Perpetuate the myth that science is getting closer to enabling real sex change.
Keep feeding the machine.
