I saw Mr. Martin at Worldcon last year. And I almost went up to him and asked, How have you gone this long without killing someone? Because however much flak I happen to get from fans, he has to get a thousand times more.
In my opinion, he's a saint. If I had to deal with that level of fan dickishness, I would have already lost my shit in some spectacular way. There would be a video of me on youtube, gone all berserk with nerd rage, holding someone up by the neck, shouting "I've got your sequel right here, bitch!"
