Okay, ignoring the fact that they have the sex chromosomes backwards, biosex genetics are not binary either. You can have trisomies or more, like XXX, XXY, XYY, or even XXYY. Or you can have only one X chromosome with no pairing chromosome.
Or, you know how in high school you learned about meiosis and crossing over? How it’s why most children of the same parents are genetically different from each other? Well, you can get accidental crossover between the X and Y chromosomes, namely the sex determining regions. That’s how you can get people with XX but develop biological male characteristics, and vice versa. It’s also why there are biologically intersex people and “hermaphrodites” (not sure of that word is PC, please let me know if it isn’t).
None of this have anything to do with gender identity though, just biological sex. But surprise surprise, science has also found real neurological, congenital, and yes, genetic factors, that contribute to a person’s likelihood of identifying as transgender, nonbinary, etc.
Then of course their fallback is that colleges are all taken over by leftists and blah blah blah. It’s like, okay, even if that’s true, they’ve still got way more scientific knowledge under their belt than your ignorant ass, so maybe approach this with some humility.
Edge cases are still real cases. It’s a proof by counterexample against the binary gender claim, which states that there are only two genders – a single example not fitting the model can be sufficient to invalidate the model, that’s how science works.
And transgender identity isn’t nearly as common as cis gender identity either. If someone can accept chromosomal abnormalities as edge cases, which are by definition, still valid cases, why can’t they do the same with gender identity?

Transphobes love to say “take high school biology” as a snarky remark against nonbinary genders/sexes. To which I say, take college biology.

Also, peer review is a cornerstone of science. Want to dispute it? Then use the scientific method to do so. Otherwise, fuck off.
