“ President Barack Obama and many liberal-minded commentators have been hesitant to call this Islamist ideology by its proper name. They seem to fear that both Muslim communities and the religiously intolerant will hear the word “Islam” and simply assume that all Muslims are being held responsible for the excesses of the jihadist few.I call this the Voldemort effect, after the villain in J.K. Rowling’s Harry Potter books. Many well-meaning people in Ms. Rowling’s fictional world are so petrified of Voldemort’s evil that they do two things: They refuse to call Voldemort by name, instead referring to “He Who Must Not Be Named,” and they deny that he exists in the first place. Such dread only increases public hysteria, thus magnifying the appeal of Voldemort’s power.The same hysteria about Islamism is unfolding before our eyes. But no strategy intended to defeat Islamism can succeed if Islamism itself and its violent expression in jihadism are not first named, isolated and understood.
