Nope, still got the wrong end of the stick there.
I'm pointing out the facts are (1) it takes of human of each sex to create another human, (2) the gestation requires a specifically female human, and (3) that second fact has had significant social consequences for women that still reverberate today.
That you assume I'm making some moral point about who gets to be parents is, I'm afraid, a you thing. You see what you want to see I guess.
I don't really care who gets to be parents or how, as long as the women who carries the child and the children themselves are safe, loved and cared for. My point is wider, and different.
I do think that the facts above, particularly the long history of social marginalisation, exploitation and abuse of the female half of humanity, means placing gender over sex is unfair because it is socially, politically and economically damaging to female people.
Now I fully acknowledge that whether social, political and ecomonic freedom of women matters in the first place is still just an opinion, but if one accepts the opinion that as far as possible we should aim to give people equal safety and equal chances to make what they can of their life, I would say it is an opinion for which a stronger practical case can be made than the alternative.
