Stranger rape is not especially uncommon, unfortunately. Something like 1 in 5 women, possibly even more, are sexually assaulted at least once in a lifetime.
Are you suggesting that geeks can't rape people? Seriously? I'm sure it's not because of their inherent gentleness or sunny dispositions. It's not because geeks aren't frequently sexually frustrated – so frustrated that they resort to asking women out to drinks at four in the goddamned morning just because they were unlucky enough to board the same elevator. Is it because geeks are weak or something? Because brother, I know more geeks who own knives and switchblades than people of any other social substratum, and knives make it pretty easy to overpower somebody in, say, a small cramped space.
If you think rape never happens on elevators, or in public places, or amidst other "males" who are "glamoring for a chance to be the hero" – well, buddy, you're starting to sound a little silly. I'm not saying you should be kicked out of a conference for asking a girl out in such a stupid, oblivious way, but Rebecca didn't have him kicked out. She just said that it "bothered" her and that she felt it was "creepy". And for that she received a lot of harassment from people just like you.
