“XX”
“XY”
“And some corruptions of those considered illness.”
The reality is that there are many women who have an XY sex chromosome. Just because you want to pretend this reality does not exist does not mean you can go around denying the actual existence of a wide variety of sexes in human biology, and there is far less excuse to go around pretending there are far more such variations in the number of sexes in the rest of the Animal Kingdom and the Plant Kingdom which are relatively normal and not to be considered to be an illness. Variations in sexual characteristics in a species and in the individual members of a species is quite common in biology, agriculture, and horticulture.
Illness. Like having 6 fingers.
