Anybody remember those SNL skits where a character named Pat was not clearly male or female, and the whole joke was how everyone was just confused about how to address them but still ended up being polite and friendly? I don’t understand how our culture got from there to people demanding proof of gender from strangers.

Unless they get creative this likely won’t do anything but piss off the human users. Research from a couple years ago found that bots are better than people at captchas.
