Chomsky, Finkelstien and all the rest

Professor Noam Chomsky was just recently denied entry to Israel on his way to speak to Bir-Ziet University. He was told at the Allenby crossing on the Jordanian Israeli border of the decision of the interior ministry that he cannot enter Israel. Professor Norman Finklestein another great lover of Zion who himself was not allowed entry into Israel was appalled by Israel’s decision. You have to wonder why.
Why would a sovereign government allow individuals who consistently deny Israel s right to exist. Who meet and openly support those who would destroy the country. Is democracy allowing someone who espouses destruction for that particular democracy the right to preach? These good professors should be surprised if entry was allowed not denied.
The crazy part of all this is that the countries and organizations that these individuals support do not have any problems of this kind. They are totalitarian in nature and few people want to visit lecture or do anything else there. These professors chose to live in an democratic environment where they can say whatever they want. This is while they support regimes that give no such privilege.
The United States would never allow an active advocate of its destruction to enter its territory nor would any other normal country. These professors should at least understand that. So you would think.
Go figure.
