I really think GC women need to let go of this fixation about whether or not men (however they identify) can carry a pregnancy. It is highly likely that, within the next 10 years, it will happen. People who say it's impossible seriously underestimate the sophistication of transplant medicine. The hormones of pregnancy can be given artificially.
If this were true we would be about 18 months away from curing all miscarriage and all infertility, but that is not the case.
The minute that a TW carries a pregnancy, that will be thrown back in our faces as 'proof' that TWAW.
I'm not trying to win a war against TW. The ability of a TW to carry a pregnancy after womb transplant that would be prohibitively expensive for all but a tiny minority does not negate my need for sex based rights.
