> how many XX people have you mistaken for XY people, and vice versa?

I have no way to know, that's my point.

Most of us have a basic biology education to drawn on that allows us to look back and in hindsight say "The men I know probably have XY and the women XX chromosones" but it's never part of the process any of us actually use.

To me, chromosones just seem like a distraction. It promises to replace all of the messy, political, social uncertainty with a polite, clinical, objective answer if only everyone would realise it's just about the biology.

The trouble is, the biology can't seem to answer the questions that are the most contentious. I have no idea what my chromosones are in reality, but I know how I'd like to live my life and mostly there's no problem, no one checks, no one asks, and if they did, how would that knowledge justify overriding my autonomy?
