Gender is compound trait assembled from a number of different underlying characteristics.
Some of the typical underlying characteristics used, such as genitalia, do have a continuous but heavily bimodal distribution. Others characteristics that may be used have a shape that has not been so well and uncontestedly defined. The selection of characteristics that goes into construction of compound trait is by no means universally agreed, not their relative weights uncontested.
“Conservatives” like to conserve what they conceive to be the correct final shape of the final trait, and would then cherry pick the characteristics and their weights so as to claim the a priori determined correct shape is not without basis.
