So much discourse is just category error masquerading as argument. The existence of a biological dimension does not make sex, race, ancestry and ethnicity equivalent kinds of categories. Social reality contains history, culture, meaning and function too.
Drawing a false equivalence between sex and race. Insanity. Funnily enough, scientific racists and ethnonationalists with their ridiculous trans comparison have been making the same argument (albeit from a racist vantage point).
