> binary reality that in adult, diploid mammals, the key chromosome pair is either XX or XY, and that every cell (except the somatic line) in that individual will have the same pair.
Unless one adopts a different definition of “individual” than the one usually applied to humans, this is wrong (germline chimerism is a thing), and right or wrong it's a weirdly narrow claims, as most cells are in the somatic line, anyway.
> The issue is that you are saying that the sexual phenotype is primary, while I claim, on the basis of biology, that the sexual genotype is primary.
Biology and medicine refer to people with phenotypical traits more associated with maleness despite XX chromosomes as “biologically male” and “XX male” (and those with traits associated more with femaleness despite XY chromosomes as ”biologically female” and “XY female”), and similarly (with variations by karyotype) based on phenotype for individuals with non-(46,XX or 46,XY) karyotypes, so even in the sense of the way biology and medicine bucket people into a forced binary, you are wrong.
And karyotype (which is what you seem to mean when you say “genotype”) still isn't binary even if you view it as “primary”, and actual genotype is even less so.
