"What's your gender?" has taken a meaning rather like the question, "What are you made of?"
"Carbon, hydrogen, oxygen, nitrogen, primal fire, smoke, mirrors, dreams, mud, star-stuff, numbers, and sterner stuff yet. And cute animal noises."
". . . ."
"Oh, and trace amounts of heavy metal, heavy metal, and Heavy Metal. And mercury, because I eat a lot of fish—"
Don't bother asking. There isn't a complete answer to be given, and all context does is restrict it until it's even less complete.
@ElectricKeet what is an acceptable current list of pronouns then? ;)
