It really boggles the mind, that someone so heavily steeped in academia, the supposed citadel of free inquiry, would try to silence anyone on any subject. But Alan Dershowitz, indefatigable champion of the Israeli cause, is willing to do that and more to anyone that dares critique Israeli policy. He has a very powerful weapon in his arsenal, in that he attempts to tar anyone who raises his ire with the "anti-Semitism" epithet. This is unfortunate on many levels, not least of which is that it weakens genuine attempts to confront anti-Semitism and racism, but also because it is a clear attempt to suppress speech which Mr.Dershowitz finds unpleasant.
He should take advice from another great champion of education, Thomas Jefferson, who advised that the cure for bad speech was more speech, not censorship. If Mr. Dershowitz finds these ideas unpalatable, he should counter them in the marketplace of ideas, not work to have them suppressed.
