These various developmental anomalies of don't map to some sort of sex continuum though - they are all discrete conditions caused by specific disorders, and from a biomedical point of view are still analysed within the framework of male and female sex development.

It's the only definition that matters when it comes to the field of biology.

The people who insist that sex is a continuum of some sort are getting confused with sex and sex-linked traits. As an example of the latter, consider testosterone levels. If you sample a random population of humans and plot this, it shows a bimodal distribution.

Some will argue that this demonstrates sex is a continuum, but what it really shows is two discrete populations that have an average difference between them: males and females.

As an example: a man with lower testosterone than most other men is not less male, or more female. He's just a male with below-average testosterone levels. The value of this hormonal trait doesn't define or alter his sex.

If it's mostly nothing, then there can't really be a problem in people not bothering to change their word usage either, right?
