That is only true if you're using an extremely idiosyncratic definition of gender. As far as 95% of English speakers are concerned, gender is defined by the body you possess.
As far as nigh on 100% of Bugis speakers are concerned there has always been five genders and they'll tell you the words in their language they have for them.
You and the other person are probably talking past each other. For most people, "gender" is merely the polite way of saying "sex", and that's probably what the other commenter was referring to.
Gender in the sense of "the social roles and norms on top of biological sex" is indeed a construct, though heavily informed by the biology that they're based on. Biological sex is very much real and not a construct.
Technically correct, but to be specific sex is binary, not merely bimodal. Sex is entirely defined by gametes, and is binary in anisogamous species such as humans. Isogamous species don't have sexes, they have mating types (and often many thousands of them).
There's actually an ideological movement to try to redefine sex based on sex traits instead of gametes, but this ends up being incoherent and useless for the field of biology. Biologists have had to publish papers explaining the fundamentals of their field to counter the ideological narrative:
That's why I thought it was worth mentioning. Many people are confused because of the culture wars. To bring it back around to the general topic of this thread, it's fine to store someone's sex as a boolean, because sex is binary and immutable. Storing cultural constructs like gender as anything other than an arbitrary string is asking for trouble, though.
Does that mean hundreds of years of English-speakers referring to sailing ship as "she" were all part of a conspiracy to hide that ships have jiggly bits? :p
Wait until you find gendered languages (like most languages in Europe) and realize that grammatical gender usually doesn't have anything to do with biological sex :P
The only real states of matter are solids, liquids, and gases. Everything else is just woke lunacy.
I am confident in this fact because I learned it in elementary school decades ago and it is impossible for humanity to discover new information that updates our world model. Every English speaker knows that “plasmas” and “Bose-Eisenstein condensates” are made up.
I assume you will be one of the advocates for my nobel prize
edit: I'm sorry you specifically mentioned gametes, we can talk about diploids and haploids if you wish and how our bodies are such complicated machines that any sort of error that can occur in our growth is guaranteed to at scale
XXY/etc are all variations within a sex. The above poster is correct to point out that sex is defined entirely by the gamete size that one's body is organized around producing in anisogamous species like humans, and is binary.
Intersex is a misleading term, the better term is https://en.wikipedia.org/wiki/Disorders_of_sex_development. There are male DSDs and female DSDs. Even in the case of ovotestes, you'll have one gamete produced, and the other tissue will be nonfunctional.
Not only have you undermined your claim to a Nobel award by showing a spurious understanding of biology, you wrote, quite sarcastically "it is impossible for humanity to discover new information that updates our world model". Well then, we will all await your discovery of that 3rd gamete, or some theory so innovative that it tips this well studied, well understood, uncontested (by any valid competitor) model to the wayside and humanity can revel in this new information, the better model of reality that you promise.
While you're at it, you could tell us all what the scientific discovery was that made gender separate from sex, who found it and when, and what the defining difference is. Did they win a Nobel for that?
I request that in any reply, you refrain from spamming me with Wikipedia links to articles you don't understand and probably haven't read.
Right, because it has. The change in gender identity (or in choosing to make said identity more public )has already taken place, and the surgery seems to affirm that.
