No. You're muddying the waters to make your position appear deep. You use the existence of very rare sexual developmental disorders to argue not only that the basic binary sexual reproductive mechanism in human beings (and many other plants and animals) is not binary when it is, but also that this mechanism somehow does not apply to people who clearly belong in either of the two sex categories (the vast, VAST majority of people).
You cannot grasp the significance of Marinov's analysis of "borderlines," aka people with disorders of sexual development, because you confuse reproductive value as determined by the capacity for an individual to pass on their genes (or not) with philosophical liberalism, the idea that all human beings have inherent value regardless of whether they reproduce. What's more, you cart out these liberal axioms (are you sAyInG TnAns pEoPle don't deServe to be fReE and HaPpY?!!!) to support a philosophical standpoint (queer theory) that is explicitly geared toward deconstructing social systems grounded in liberalism.
Human sexual development is a complex multivariate phenomenon that nevertheless unfolds in a predictable way for nearly all human beings. This binary pathway of sexual development is essential to reproduction in human beings. People whose development deviates from this pathway, such that they productive neither sperm nor eggs, cannot reproduce. There ARE exceptions, but these exceptions prove the rule.
