Gimme a match and I'll check the gas tank.

You expect me to believe a crappy video is making people go on murderous rampages because they feel they've been insulted? Why didn't every new Jerry Lewis movie cause chaos on the short bus? How come the first episode of the Beverly Hillbillies didn't spark violent riots all across Appalachia? Why haven't we seen James Cameron's head on a stick? What I'm saying is, you don't want to focus too much on a single trigger event. Gavrilo Princip was not the mastermind behind the collapse of four or five empires any more than yodeling has the power to create avalanches.
