I don't think anything will happen on the scale of the Anarchists of the early 1900s, or Jihadists... Even though Europe has it's fanatics, their views are far from accepted by the majority-- You know the saying "Desperate times requires desperate measures."? People in the west really aren't that desperate-- not yet anyways, people may agree with what he's spouting; but I don't foresee this being a weekly/monthly/or even yearly thing... the average nutter needs more substance than what he's put forward.
