I honestly don't get the agender stuff and I legitimately think that they should have their own separate thing than trans people (given they are agender and we aren't), but I haven't seen a single study suggest the data you're suggesting. Sociologically, there's more than male or female. When you say there's only male or female do you biologically or sociologically? Because I have already made the case for sociological gender variety. Two spirit, third gender;etc have existed as long as there's been humans. Biologically, intersex is a thing. So when you speak biologically do you really mean sex and not gender? So I'm not really sure what you're arguing nor how you could possibly use science to argue it since there's no data on agender either for or against.
From the article you listed earlier:
With most mammals, however, the majority of individuals are cisgender male or female; transgender individuals are estimated to comprise about 0.3% of the adult U.S. population.
And intersex is estimated at about 1.7%. You can argue stuff like XXY, but a lot of those chromosone variances still fall along male/female.
So intersex and transgender are out there, but they are very small. The point being that there's a 98% group that is male to man and female to woman. I know cultural anthropology has cultures that have a third gender and that America is very binary with gender. However, its still a matter of statistics. We got from 2 genders to maybe 3 genders, but we're still dealing in small, small portions on that third gender. Even within those portions, transgender often exists at the poles but at both ends at once. Male/Woman Female/Man rather than Male/Man or Female/Woman.
So it's not an argument that such things don't exist, but a criticism of the portrayal of their prevalence. In the populace, we have four polls. Male, Female biologically and Man, Woman as gender. Biology largely informs gender. There are people in the middle and some of those people are still at the polls just at both opposite polls at once. So that's how you get 98% of the population as cisgender and even those that are transgendered can exist at the two ends with "traditional" genders that just don't match biological sex at birth. So a multitude of genders isn't backed up by stats or studies. It's largely the two big categories.
So when people say gender spectrum and people envision this granular continuous range, they are envisioning a false idea of the reality. The reality is two large piles with a little bit in between, but even the in between is sometimes made up of the identities in the large piles.
