This runs contrary to your claim.
I am principally chiding you for your sloppy logic and poor grasp of facts here, to be clear.
Intersex people are more common than gold.
And it is a fact that humans have zero, one, two, or more legs. But you would never argue with the scientific claim that humans are a bipedal mammal. The exceptions do not invalidate the norm.
> This runs contrary to your claim.
It does not run contrary to my claim. My claim is that humans are either male or female. And this is wildly, overwhelmingly true.
I don't feel any need to qualify the statement that humans are two-legged creatures either.
There are exceptions in both cases, but they're not the norm.
> Intersex people are more common than gold.
It was your damn analogy, not mine.
Normal: conforming to a type, standard, or regular pattern : characterized by that which is considered usual, typical, or routine.
Gold is not normal material in the crust. The crust is not gold. Gold is not the crust. And it is normal to have a penis (male) or a vagina (female).
This has nothing to do with what we value, be it rare or otherwise, it has to do with biological facts.
