Well, that sounds like a you thing, not an everyone thing, doesn't it.
It sounds like a thing with almost everyone I've ever spoken to.
I'm not saying that other people can't have genders - I'm saying that I (and many, many other people, and the dictionary) define woman as 'adult, human, female'
I'm saying that I am a woman, the vast, vast majority of people identify me as a woman, yet, according to your rules, you're saying I'm not one, because I don't have a gender.
I'm saying that my children don't seem to have genders, my partner doesn't think he has a gender, neither do my sisters. Laverne Cox apparently does.
Does that mean that only Laverne Cox is a woman out of all of us? That there's no difference between my sister and I, and my partner and male children?
That's patent nonsense. The entire world would recognise me and my sisters as female, and my partner and sons as male, and there's nothing wrong, or weird, or unexpected about that.
