Of the 7 indicators determining biological sex that are listed in para 5 of Bellinger v. Bellinger, I lack 2, 4 of them are those of a woman and 1 of them is unknown (but likely that of a man). My biological sex is far more woman than man. publications.parliament.uk/pa/ld200203/...

I've increasingly seen the terms "Biological [male/female]" used to talk about trans people, even by people trying to be supportive, and I wanted to get my thoughts down about that. The tl;dr is that the terms are slurs and factually wrong, and pushing back when you see them is appreciated.
