Wrong. Gender is make-believe; biology is real. I go by what is real. With 100 different genders, I can’t look at somebody and tell if they are Aporagender, Bigender, or any of the countless other genders people dream up; maybe you can but I can’t. But I can look at them and tell with pretty good success if they are male of female.
Again; when I refer to somebody as he or she, I am referring to their biology; not their gender. I do this with all mammals be it my dog, a cat, or human.
Gender is very real. People have been killed over gender. Gender refers to the social expectations that a culture attaches to biological sex. The idea of what is appropriate appearance and behavior for a man or women is "gender".
