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.
Reproductive sex is determined by gametes .. sure.
Not all humans are born with the attribute of reproductive sex via gametes.
Hence "biological sex is real and strongly bimodal with outliers" (in humans, it gets odder elsewhere in animal life on earth) it's just not all reproductive sex, nor is all just strictly M or strictly F despite it mostly being one or the other.

Not in Australia, via a decision that ascended through all levels of the national court system, nor is sex, as you've chosen to define it ("entirely defined by gametes") binary.
Biology is truly messy. It's understandable not everbody truly grasps this.
Colin Wright is pretty much a prop up cardboard "scientist" for the Manhattan Institute (a political conservative think tank).
I tend to run with people with actual field credentials doing real biology and medicine; Michael Alpers, Fiona Stanley, Fiona Wood, et al were my influences.
If Colin Wright scratches your itch for bad biology then by all means run with the one hit wonder who reinforces a preconception untroubled by empiricism.
You can't legislate reality away. If you're tracking biological sex, then it doesn't matter what a court decides. If you're tracking legal fictions then you might.
I look forward to your citation disputing the truth of what he lays out in that paper. In the meantime, feel free to peruse the list here of people affirming the same stance:
You should ask the people you run with why no human is born with a body not organized around the production of gametes. You'll notice that when you read about conditions like anorchia or ovarian agenesis, the sex of the person with that condition is not a mystery, it's literally in the name.
Biology is messy indeed, and that's why finding such a universal definition was so useful.
