There's nothing anyone in civilized western Europe can do. Not with PC and multi-culti loons running the show. If this keeps up, islam attacking and limp-writed liberals retreating, it's gonna cause a backlash that will see the Far Right come to power. Then God himself can't save the muslims.
I don't think you will ever see a backlash in Western Europe. Two World Wars + Socialsm have pretty much emasculated the Europeans. They can't even muster the will to reproduce themselves.
