If it doesn't, choose the other or closest option. It's unlikely there isn't one.

Sure, like here in NYC. That's really more of a personality thing IMO, which gets conflated with sex. Wherever necessary, things still reduce down to a binary choice, with the rest being details.

... And if you're intersex, what then?

[kennysoona]

Intersex people still generally fall on one side of the binary in how they identify and/or present, so they can choose the closest option.

"Generally", means there are exceptions to the rule. If the ancient Greeks could handle more than two, can't we, today?

[kennysoona]

I'll retract that 'generally' then, and substitute it with 'always', since that's a mathematical certainty. There won't be any humans that are perfectly balanced with a completely equal distribution of all traits that we assign to one of the binary choices. Barring that, someone will always fall on one side.

Sure, though, we have the tech and ability to handle more than two, but until we get to the point where that's the norm not every situation where we don't isn't one where the sky falling.
