I once ran into a person (online) who said, "When someone asks me if I'm a boy or a girl, I ask them, 'What do you think?' and however they answer, I tell them they're correct."
I want to be like that person.
It's hard being that way offline, though. Particularly because I want to be seen as a person, not as an ambiguously-gendered object. I don't necessarily want my first impression upon everyone to be "What is this person? Which head-box do I put them in? What pronouns do I use for them??"
I've been toying with the idea of asking people to call me "he/him" just to see how it feels. Otherwise I'm ok with she and ze, also. I know what I am inside; you can call me whatever makes you comfortable, since I am both male and female. That's how I see it.
