As always, we have to see the carnage as yet another sign of the sheer and utter inability of the muslim world as a whole to come to terms with the reality of its own worthlesness. Humanity wants to move on. Islam can't. And at least subconciously muslims know it.
Explain away what you want - the only valid conclusion is that there is no place for islam on this world.
Say a prayer for the victims of this callous act.
