The question, then, is whether a given person is just an outlier by coincidence, or whether the underlying causal mechanisms that created their personality actually are coming from some internal gender-variable being flipped. (The theory being, perhaps, that early-onset gender dysphoria is an intersex condition, to quote the immortal words of a certain tribute band.)
If it was just that biological females sometimes happened to have a couple traits that were masculine—and these traits seemed to be at random, and uncorrelated—then that wouldn’t imply anything beyond “well, every distribution has a couple outliers.” But when you see that lesbians—women who have the typically masculine trait of attraction to women—are also unusually likely to have other typically masculine traits—then that implies that there’s something else going on. Such as, some of them really do have “male brains” in some sense.
And there are so many different personality traits that are correlated with gender (at least 18, according to the test mentioned above, and probably many more that can’t be tested as easily) that it’s very unlikely someone would have an opposite-sex personality just by chance alone. That’s why I’d guess that a lot of the feminine “men” and masculine “women” really do have some sort of intersex condition where their gender-variable is flipped. (Although there are some cultural confounders too, like people unconsciously conforming to stereotypes about how gay people act.)
I completely agree that dividing everyone between “male” and “female” isn’t enough to capture all the nuance associated with gender, and would much prefer that we used more words than that. But if, as seems to often be expected by the world, we have to approximate all of someone’s character traits all with only a single binary label… then there are a lot of people for whom it’s more accurate to use the one that doesn’t match their sex.
