Thanks for speaking up! You've made an excellent point about race being far more of a spectrum than sex. In over 25 years of pediatrics, I've yet to see a newborn with truly ambiguous genitalia. Such a thing can happen, but is vanishingly rare.

For the curious, I'm well aware that gender can be called a social construct, but I'd prefer if forms use something like "gender identity" and also use sex. The numbers of "women" committing sex crimes in England and Wales have recently almost doubled - this appears to be due to the fact that police departments are recording the gender rather than the sex of perpetrators.
