The biker rebellion
Well, it's starting to happen -- and perhaps predictably, it's starting in Denmark, which has been more resistant to this pestilence than other western European countries (recall for example the battle of the Muhammad cartoons). Biker gangs, apparently, are the vehicle chosen by the young to bypass their quavering elders' sclerotic political system and strike back at their tormentors.
The above link was pointed out to me by Mary Madigan, who says: "Actually, a protest in Denmark might be equivalent to a protest in the Middle East. Many of the riots involve Muslim criminal gangs vs. Danish criminal gangs like the Hell’s Angels. Lots of young Danes are joining the Hell’s Angels, even though they don’t have motorcycles, for an opportunity to fight the Muslim gangs."
I suspect we'll be seeing a lot more of this phenomenon. There are plenty of angry young non-Muslim males in Rotterdam, Sheffield, Marseilles, Hamburg, Brussels, Rome, and on and on. Maybe it won't be biker gangs in those places; maybe it will be something else. But human nature cannot indefinitely tolerate being bullied and threatened by arrogant aliens on one's own turf.
