Nevermind that business about rock terrorism. And forget what I said about bald terrorism. I didn't see it until just now: The Sikh killings perpetrated by Wade Michael Page can be traced to facial hair. This was Goatee Terrorism.
Mark Juergensmeyer has called it "Christian terrorism," but this is plainly wrong. Has any one noticed how many criminals have facial hair? Just go watch a TV police drama and you'll see.
