The best theory about the trans movement I've heard is that they want a "woman" to be legally defined as anything but what a woman actually is, i.e., two XX chromosomes, wider hip bone, how their bodies use estrogen, uterus, breasts, vagina, etc. Think about this in terms of their desperation to control population and connext the dots.
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.
@UncleIroh @nomebullyyou Per Wikipedia there's a grand total of five hundred known cases of intersex "true hermaphrodites."
Most, maybe the vast majority are XX. I'd guess a bottom line is there's only so much weirdness biologically that can happen in making a human that the ones who survive to birth are rare enough. For example plenty of bad gene combinations and mutations are quickly fatal; it's kinda amazing how well it actually works.
