The fact that they were CONCEIVED male, developed embryologically male, were born male, grew up male, etc., means they were biologically set on a certain developmental pathway that cannot be UNDONE.
That capacity is one of THE essential capacities of women. In biological terms, that is what DEFINES “female” vs “male.”
There is ZERO “transphobia” is noting the reality that trans women lack certain properties that all biological women (barring accidents) HAVE—particularly reproductive capacities.
ALL biological men, trans or regular, are ESSENTIALLY unable to do this. Men can ONLY be fertile by BEGETTING.
Would such technologically produced women be regarded as women, full stop?
Despite being INDISTINGUISHABLE BY ANY MEANS, they are still regarded as not as valuable.
Make of that what you will.
