Not only are we expected to somehow ignore millions of years of human evolution where our ability to detect the sexes, and especially the opposite sex, is integral.
But we're also now meant to seamlessly ID someone not as the opposite sex, but no sex at all ie NB.
All in the space of mere split seconds if you put the span of human existence on a 24 hour clock.
Of course our friend here has no problem locating millions of years of human evolution in unrestrained violence, and violence on women.
THAT'S totally consistent with our existence as humans. What's not consistent is the demand to ignore biology and evolution.
