It is remarkable that a 'clinical neurologist' makes the claims that he does in this article. He is all about 'sex is bimodal' without ever providing the labels for the axis.
For a start, he also makes this claim:
"there are XY females who are chromosomal males but develop mostly or entirely female because of androgen insensitivity."
When the reality is that we already know that some people don't fit a strict 'chromosomal' category. That doesn't make them 'mostly' one sex! FFS.
This dude lectures at Hale AND is apparently a 'skeptic'.
Then it goes into, as expected:
First we need to consider all the traits relevant to sex that vary along this bimodal distribution. The language and concepts for these traits have been evolving too, but here is a current generally accepted scheme for organizing these traits:
• Genetic sex
• Morphological sex, which includes reproductive organs, external genitalia, gametes and secondary morphological sexual characteristics (sometimes these and genetic sex are referred to collectively as biological sex, but this is problematic for reasons I will go over)
• Sexual orientation (sexual attraction)
• Gender identity (how one understands and feels about their own gender)
• Gender expression (how one expresses their gender to the world)
He also quotes the misinformation that is 1.7% of people are "intersex" as being an accurate reference.
He then conflates 'having sex' with the human sex categories, yet he then describes categorising human sex categories being about reproduction as being 'reductionist'.
"The argument often goes that sex is only about reproduction, and since gametes are binary, sex in total is binary. This is incredibly reductionist, and misses the fact that traits often simultaneously serve multiple evolutionary ends. Sex, for example, is also about bonding, social relationships, power, and dominance. Think about this – what percentage of the time that humans have sex is the express purpose reproduction? How many people have no desire to ever have children, but still have an active sex life? Can there be romance without sex? Why are there so many aspects of sex that are not strictly reproductive?"
Apparently now, sexual orientation is relevant to sex categorisation and whether sex is binary. Partly because of arousal patterns (well, no shit - penises and clitorises react differently to arousal)
"One brain feature that gets a lot of attention, however, is sexual orientation. I know I am framing this with a conclusion that some people contest, that sexual orientation is essentially determined by brain development, but that is the current consensus of scientific evidence and opinion. People are generally born with their sexual orientation, even if it is not fully realized until they go through puberty. In fact, I would consider sexual orientation to be part of biological sex (which is why I divided up sexuality as I did above)".
and
"If, then (as seems clear), sexual orientation is a brain function largely determined by genes, hormones, receptor sensitivity, and other epigenetic factors all affecting brain development and physiology, then it’s reasonable to consider sexual orientation an aspect of biological sex also."
I am sure that this will be a surprise to any lesbians reading this. Apparently, being a lesbian will influence what sex category you belong to.
What a remarkable article.
