This week, The New York Times published a column by a left-wing academic (forgive the redundancy), John Della Volpe, director of polling at the Harvard Kennedy School Institute of Politics.  In his first sentence, Mr. Della Volpe reveals his politics. He described young Americans as "stressed and sickened by thoughts of their rights and democracy slipping away."  That is what Harvard and just about every other university tells America's young people: "Because of the Right, you should be stressed and sickened -- the Right is taking away your rights and destroying your democracy."  The terrible irony is that there is a mortal threat to Americans' rights and democracy -- but it is entirely from the Left. Ever since Stalin declared Trotsky a "fascist," the Left has labeled its opponents precisely what the Left itself is.
