First of all, I didn't say anything about gender. Secondly, gender can be whatever you wish it to be because you can pretend you're a f*cking dragon and then call it a gender. But calling it a gender doesn't make it a gender as has been defined since the beginning of human existence as male and female.
I knew someone who "identified" as a cat. She implanted whiskers on her upper lip and got cat eyes contacts. In today's social constructs that would be considered a gender. It is not.
It isn't a gender just because you say it is. Male and female are genders. Everything else is just made up and the definitions are changed to fit a minority's belief of what truly constitutes as gender.
