I’m just picturing that robot from Star Trek (the one thinking about “this sentence is false”) going “huh” and then blowing up…

It actually is really simple. If you’re born with XY chromosomes, you’re a man. If you have XY chromosomes and ambiguous genitalia that can look like a vagina, then you’re a man with a Disorder of Sex Development (DSD).

Men with DSDs will often have elevated testosterone levels because they also have testicles, sometimes underdeveloped and/or undescended. That’s not what makes them a man though, it’s their XY chromosomes.

that’s, like, a third graders understanding of biology and reality is nowhere near that convenient
What is incorrect about it?

That gender is at least partially a social construct and even if you have XY chromosomes and you’ve been brought up as a woman you shouldn’t be forced to live as a man in case you do a chromosomal test and it turns out you have XY chromosomes.

Imagine the opposite - you’re an XX man with a penis and you’ve lived as a man your whole life and then you do a random chromosomal test and somebody tells you “you see I know you have a penis and I know you’re fine being a man but your chromosomes says you’re “female” so we have to chop off your dick ans grow titties so you can fit into the binaries we’ve established because it’s too hard for others to believe you’re a man”
