This rubbish puts me in mind of Monotremes.
Most mammals have 2 sex chromosomes: females are XX, males are XY. (And from sex comes gender.) Three species, however, the Monotremes (platypus, echidnas) have many more: 9 or 10. And yet still, there are just two sexes. #evotruthhttps://twitter.com/BretWeinstein/status/943930706450833408 …
I think characterizing that as the "whole feminist schtick" is dishonest at best. Esp. In this context given the origin of the term incel in self-identification by misogynist MRA online communities. If anything, it mocks that concern precisely.
