-This is a severe misreading of the sex-realist position. No one wants to _define_ "gender" based on psychology. Definitions don't matter: you can't coerce reality into changing by choosing different definitions! Rather, there's _already_ a multivariate distribution of bodies and minds in the world, and good definition choices help us coordinate the concepts in different people's heads into a _shared_ map of that territory.

+_One_ of the _many_ distinctions people sometimes want to make when thinking about the multivariate distribution of bodies and minds in the world, is that between the sexes. But sex is by no means the only way in which people differ! In many situations, you might want to categorize or describe people in many different ways, some more or less discrete _versus_ categorical, or high- _versus_ low-dimensional: age or race or religion or subculture or social class or intelligence or agreeableness.

+It's possible that the categories that are salient in a particular culture ought to be revised in order to fit the world better: maybe we _should_ talk about categories like "masculine people" (including both typical men, and butch lesbians) more often! But the typical trans advocate shell game of just replacing "sex" with "gender" and letting people choose their "gender" isn't going to fly, because sex actually exists and we have a need for language to talk about it—or maybe, the fact that we have a need for language to talk about it (the fact that the information we observe admits compression) is what it means for sex to "actually" "exist".
