"And we create another legal fiction. One that would effect the human rights of every child born in this situation. I believe a child has a fundamental right to know their biological parentage. My father was haunted by not knowing his. I hope parenthood makes Freddie understand their feelings aren't the most important thing here."
Not a legal fiction, perhaps but a language fiction.
Freddy, in gender terms, is a man. Man is his gender construct, he lives as a man, presents within a masculine gendered construct. Grows a beard, does his best not to look 'soft' and scrawny', wears clothes aimed at the masculine stereotype.
Biologically Freddy is female, and does indeed have the large gamete. The child will know that Freddy is a biological mother, but is living the gender construct of father. If Freddy tries to say that gestating a child and giving birth is a male biological function then that is the fiction - but still a fiction of language. The child will have no more or less access to knowledge of bio parenting than any other child born of donor eggs or sperm.
As words we use father and mother equally to mean the social function and the biological function.
I also didn't take Freddy's relationship with his own body to mean disdain for other women's bodies. Or other women. He was honest that it was uncomfortable for him to have to return to some more feminine-assigned clothing etc, because of his Trans status. Not because he was hostile to women.
Why do we need to pick apart the details of his relationship with CJ. Freddy said it was complex, and 'queer'. CJ seemed lovely. People can have all sorts of relationships. I'm glad they stayed friends.
I see time and time again that GC women are not transphobic against Trans people just because they are Trans. So what is the problem with an individual Trans person living their life as such, and making the individual choices that make their lives possible and happy.
