At no point on the Quigley scale does anyone approach being the opposite sex or a third sex.
And yet it is clearly a spectrum rather than a binary, which was my point.
Genital morphology isn't sex.
Sex is an idea (or a set of ideas) which we use to describe the world; many people do in fact think of it as determined by genitals. Any skeptic publication concerned with promoting scientific understanding of the topic should at some point address this naive sense of what people think "sex" should be taken to mean.
you should know it and be resistant to being gulled by charlatans selling snake oil.
This is an incredibly uncharitable characterization of someone who has produced
hundreds of hours of scientifically sound content for the skeptical community, based on one issue where he clearly goes awry—along with most practitioners in his field.
Quigley scale that you reference is only applicable to males.
For purposes of public policy (which
@Ziggurat insists is the real crux of the topic here) are you entirely comfortable with treating CAIS individuals on one end of that scale as males? Putting them in male prisons, for example. This idea strikes me as needlessly cruel, but I'm interested in hearing your take on how genetic maleness should intersect with public policy in such a case.
It doesn't demonstrate that you're smart, that you understand complexity and nuance, it just shows you're more interested in sophistry than the actual relevant questions that people actually care about.
Trying to demonstrate that complexity and nuance actually
exist (e.g. in the policy question of where to put CAIS or PAIS prisoners) is not the same as trying to demonstrate one's own understanding. You have made the common mistake of addressing the arguer rather than the argument.
All that's needed to support Novella's claim is to show a single human being with a reproductive system that has evolved to support the production of either 1) a mixed gamete, or "sperg" if you will or 2) a unique third type of gamete.
3) A single human being who was never on a developmental path to produce
either gamete and therefore cannot be classified using the gametic binary.
there is sex - the evolved role within anisogamous species.
Individuals who are congenitally incapable of producing either gamete do not have
any reproductive role in an anisogamous species. If you want to show that Novella is wrong about being able to classify every individual as either male or female, you'll have to show that everyone who has never produced any gametes is nonetheless classifiable using something other than gametes.
