Yeah, the binarist answer to enby existence is "give them a special box they can check!" as a way to, like, even the score. And not actually inspect why there are even gender boxes on the stuff we're talking about anyway. Same goes with bathrooms. I mean, sure, you can build a third, all access bathroom. Or you could just rip the signs off your doors and go about your day. Eliminate gender, don't just give us an "other" option.
