Too bad those definitions don't agree. XXY is considered male. Hermaphrodite can be determined. Dark, if anyone's qualified to know what they're talking about, it's Pinkie, and they disagree.

They literally all agree that sex <> gender. Gender is not fixed nor biological, and it's not like tumblrites claim it is. Dictionary says so, science says so, medicine says so, and a brief look at gender roles through cultures through history will say so as well. This is not difficult.

True, hence why I keep saying technically. Hermaphrodites do exist that are not like you claim, but are completely equal in both XX and XY. That's why it's a sex itself.

My gods man, do FIVE MINUTES of research and you'll be smarter than 90% of americans on this subject. Hermaphrodites are considered a sex because they fucking appear in other species than just humans. The fact that humans exist that are hermaphrodites isn't even important, really. 

And no, pinkie really isn't qualified to know what he's talking about with this. I can kinda see why you say so, but he's not.
