Where is this 6 sexes bullshit coming from? First a Texas senator and now this idiot.

it's because there was an article going around about the 6 most common human karyotypes (= combination of X and Y chromosome). What they're not saying is that 1. 4 of those are quite rare and 2. They can all still be clearly assigned to one of the two human sexes.
