Earlier quoted context omitted.
Yes! Exactly that's the point. Biology's complicated, of course there are edge cases. That in no way alters the fact that the core concept is that a woman is an XX human. Re infertility, don't be silly. Yes I didn't word it perfectly, I meant "XX, i.e. the sex that bears children in mammals". Do you know what anisogamy means? This stuff wasn't complicated 20 years ago and funnily enough the science hasn't changed.
> I meant "XX, i.e. the sex that bears children in mammals". There are fertile XY females among mammals (including humans.)
But in any case, the point is that biology is messy and always has rare exceptions. As an engineer I’m sure you appreciate the value of simple definitions that capture 99% of the diversity accurately.
