Ugh. One of the things Twitter's blowing up about is that this occurred after a 9 year old girl presented her hack. I'm one of the 'privileged young white males' people love to talk condescendingly about, and as someone fairly new to the tech scene I had thought all the sexism hand-wringing was a little blown out of proportion, but...really? Blows my mind that there really are people who think this is okay/funny and that the adults in charge didn't serve as an (unfortunately necessary) line of defense against this asshattery.
