Some people feel strongly that they have a fixed gender, but my gender feels more like a performance. When I do my nails, for example, I’m performing a certain American version of femininity. When I’m playing sports, I’m performing a particular version of masculinity (though these things aren’t inherently feminine or masculine).

When I’m writing about non-binary identity, I’m performing one form of that gender. When I wear androgynous clothes, I’m performing another form.

It’s not fair to expect everyone to have only one gender when gender means so many different things in different cultures and subcultures to different people.

When it comes to your gender, nothing is disallowed, as long as you’re not hurting anyone. And the only way your gender identity can ever hurt anyone is if you try to impose it on somebody else. I’m no longer letting people do that to me.
