Columbia is experiencing a virulent dispute that has rattled the university for months over alleged intimidation of Jewish students by pro-Palestinian professors in the Middle East and Asian languages and cultures department. A faculty task force is investigating the dispute. Professor Massad, a Palestinian, said he's received hate mail calling him a "camel jockey" and "Islamic Fascist." Tommy Schoenfeld, a student who had served in the Israeli Army, says when he tried to question Prof. Massad at an off-campus lecture, his question was met with, "How many Palestinians have you killed?"
