With the #IStandWithMaya matter it's worth revisiting this Colin Wright article on recent efforts to deconstruct biological sex

We can acknowledge the existence of very rare cases in humans where sex is ambiguous, but this does not negate the reality that sex in humans is functionally binary. These editorials are nothing more than a form of politically motivated, scientific sophistry.

The formula for each of these articles is straightforward. First, they list a multitude of intersex conditions. Second, they detail the genes, hormones, and complex developmental processes leading to these conditions.

And, third and finally, they throw their hands up and insist this complexity means scientists have no clue what sex really is. This is all highly misleading and deceiving (self-deceiving?), since the developmental processes involved in creating any organ are enormously complex,

yet almost always produce fully functional end products. Making a hand is complicated too, but the vast majority of us end up with the functional, five-fingered variety.

What these articles leave out is the fact that the final result of sex development in humans are unambiguously male or female over 99.98 percent of the time. I'm an amodal one (one in which no specific outcome is more likely than others).

Biological sex in humans, however, is clear-cut over 99.98 percent of the time. Lastly, the claim that classifying people’s sex based on anatomy and genetics “has no basis in science” has itself no basis in reality, as any method exhibiting a predictive accuracy of over 99.98

percent would place it among the most precise methods in all the life sciences. We revise medical care practices and change world economic plans on far lower confidence than that.

Despite the unquestionable reality of biological sex in humans, social justice and trans activists continue to push this belief, and respond with outrage when challenged. Pointing out any of the above facts is now considered synonymous with transphobia.
