The problem with those definitions, as obvious and true as they are, is that trans activists have found examples that contradict the XX argument.
What they cannot and have never been able to refute is that every single person on earth develops 1 of only 2 reproductive capacities, male or female. It doesn't matter if their reproductive system is functional, just that their bodies have matured into 1 of 2 options.
That also goes for the rare intersex types.

Exactly. You can legit tell an intersex person to go fuck themselves, but they can't get themselves pregnant.
