[It's true that there are some folks, though the numbers are very small overall, who have some of all of the organs of both sexes and then have to sort it out further, but again, that's not, shall we say, usual.]

But the point is it's not a hard-and-fast division. I don't see the need to thrust a binary upon the situation.

We're each enslaved to our own unique biology; there's no arguing with that. What I don't accept is that we need to be enslaved to categories as well.
