Abolish male supremacy not binary gender

The basic gender binary is an analogy to binary sex in all human societies, indigenous American and all around the globe. Hermaphroditism , homosexual , transvestitism have been incorporated forever, not just since the bourgeois "trans" fad. But third genders don't demolish the basic binary, because biology has an absolute binary - eggbearers and sperm bearers. There are no third types. So , the basic binary pair female-male: woman-man, remains even as third genders are added. 

The goal is abolish male supremacy, not binary gender.

Different combinations and numbers of X and Y chromosomes do not produce a third type of gamete cell, so they all result in one of the two sex cell types if they result in a sex cell type. Sex is ultimately a phenotype , not a genotype.
