Because we have biological evidence for a sexuality which is richer than his socially-constructed binary sexuality. Specifically, we know about intersex [0] chromosomal arrangements, and we know that they don't just neatly fall into male and female arrangements. We might expect of university professors that they grok the basis of their field, and what they're actually studying. When somebody insists that they ought to be tenured, we ought to double-check that they understand science. The Nature memo that he complains about [1] merely says that the Trump administration is incorrect to think that genitals determine chromosomal layout, and a brief sanity check shows that indeed it should be entirely the other way around, and even then, chromosomes don't guarantee that genitals will develop a certain way. The author groks this critique and doubles down; in [2] he insists that intersex people are less than 0.02% of the population, and thus don't matter. That should show you exactly how unscientific he is; he points to his degree over and over as evidence of his quality, but fails at hard numbers. Meanwhile we estimate XXY chromosomes [3] and XXX chromosomes [4] to occur in around 0.1% to 0.2% of the population, and that's just one of dozens of possible chromosomal arrangements. (Or two, I guess, depending on how one counts.) He is at least an order of magnitude off, possibly more, and doesn't care because it would require him to back down from the hill he's chosen.
