... is not a binary, but rather a spectrum with many variations. They're just kind of hard to see when doctors routinely cut off genitals they find offensive. It particularly aggravates me when people argue the "isness" of gender not based on scientific fact but a casual glance at the crotch, which is often wrong in intersex cases. At least a chromosome reading would tell you what the sex chromosomes say. Which is sometimes XXY, XYY, X0, or other things that aren't the standard male or female -- leaving those people legally obligated to lie about their sex on almost every form, which only offer male/female in official contexts. Someone really needs to sue the government for rampant sex discrimination. I mean, imagine if the forms only offered "male" and all women had to lie or go without services. They'd be as pissed as they were back when a lot of places had only men's toilets.
