You seem like you should know better. From the first link:

Instead, most characteristics ascribed to males and females fall along a spectrum with two peaks, one the average for females and the other the average for males. For instance, on average, males are taller than females and have more muscle mass, more red blood cells and a higher metabolism.

But almost nobody fits in the peak for all those measures for their sex, Lents says. “There’s plenty of women who are taller than plenty of men. There are plenty of women who have higher metabolic rates than some men, even though the averages are different.

“If you define biological sex purely on the gametes, you’re going to ignore most of what actually matters to your daily life, including in your social life,” he says. “Reducing sex to a binary really doesn’t make a lot of sense for how we actually live.”

It confuses sex phenotypes with sex, which is a basic error. That's not how sex is defined, it's defined entirely by gamete size because no other definition makes sense.

Intersex is a confusing term, because you will either have a male or female DSD

Your other links are talking about variations within a sex. You also misunderstand how sex is determined vs how it is defined.
