This is not a matter of whether or not you agree with Chomski's views. It's a matter of freedom of speech - which I used to think was one mitigating circumstance in Israel. At least you were allowed to speak your mind! But obviously no more... It is now so scary to let people into the country that clowns of many colors have to be stopped at the border.
