But seriously, you thought the Arcade Fire fans were douchebags? I barely noticed anything remotely resembling that. Most people I met had already seen Arcade Fire before and were there to hype up other bands. The biggest douchebags were the hardcore moshing morons at Manu Chao that were obviously only there to see Rage.
I did see some people crying after the AF set, but that's hardly douchebaggery.
