George Packer’s response is precisely right:
The murders today in Paris are not a result of France’s failure to assimilate two generations of Muslim immigrants from its former colonies. They’re not about French military action against the Islamic State in the Middle East, or the American invasion of Iraq before that. They’re not part of some general wave of nihilistic violence in the economically depressed, socially atomized, morally hollow West—the Paris version of Newtown or Oslo. Least of all should they be “understood” as reactions to disrespect for religion on the part of irresponsible cartoonists.
They are only the latest blows delivered by an ideology that has sought to achieve power through terror for decades. It’s the same ideology that sent Salman Rushdie into hiding for a decade under a death sentence for writing a novel, then killed his Japanese translator and tried to kill his Italian translator and Norwegian publisher. The ideology that murdered three thousand people in the U.S. on September 11, 2001. The one that butchered Theo van Gogh in the streets of Amsterdam, in 2004, for making a film. The one that has brought mass rape and slaughter to the cities and deserts of Syria and Iraq. That massacred a hundred and thirty-two children and thirteen adults in a school in Peshawar last month. That regularly kills so many Nigerians, especially young ones, that hardly anyone pays attention.

A religion is not just a set of texts but the living beliefs and practices of its adherents. Islam today includes a substantial minority of believers who countenance, if they don’t actually carry out, a degree of violence in the application of their convictions that is currently unique. Charlie Hebdo had been nondenominational in its satire, sticking its finger into the sensitivities of Jews and Christians, too—but only Muslims responded with threats and acts of terrorism. For some believers, the violence serves a will to absolute power in the name of God, which is a form of totalitarianism called Islamism—politics as religion, religion as politics. “Allahu Akbar!” the killers shouted in the street outside Charlie Hebdo. They, at any rate, know what they’re about.
And of course, what follows from this is the observation that if one fails to speak out against the murders, one is, quite frankly, part of the problem.
