Los Angeles, April 30, 2009: Controversy has erupted at University of California, Santa Barbara, over a professor's decision to send his students an e-mail in which he compared graphic images of Jews in the Holocaust to pictures of Palestinians caught up in Israel's recent Gaza invasion.

The e-mail by tenured sociology professor William I. Robinson has triggered a campus investigation and drawn accusations of anti-Semitism from two national Jewish groups, even as students and faculty members have voiced support for him.

The uproar began in January when Robinson sent his message - titled "parallel images of Nazis and Israelis" - to the 80 students in his sociology of globalisation class.

The e-mail contained more than two dozen photographs of Jewish victims of the Nazis, including those of dead children, juxtaposed with nearly identical images from the Gaza Strip. It also included an article critical of Israel's treatment of the Palestinians and a note from Robinson.

"Gaza is Israel's Warsaw - a vast concentration camp that confined and blockaded Palestinians," the professor wrote. "We are witness to a slow-motion process of genocide."

Two Jewish students dropped the class, saying they felt intimidated by the professor's message. They contacted the Simon Wiesenthal Center, which advised them to file formal complaints with the university.

Robinson, 50, who is Jewish, called the accusations and the campus investigation an attack on academic freedom. He said his former students, the Wiesenthal Center and the Anti-Defamation League had all confused his criticism of Israeli policies with anti-Semitism.

"That's like saying if I condemn the U.S. government for the invasion of Iraq, I'm anti-American," he said. "It's the most absurd, baseless argument."

Robinson said he regularly sends his students voluntary reading material about current events for the global affairs course, and that no one raised questions when he subsequently discussed his e-mail.

"The whole nature of academic freedom is to introduce students to controversial material, to provoke students to think and make students uncomfortable," said Robinson, a UCSB professor for nine years.

Robinson's supporters say the professor is being maligned for exercising his right to challenge his students to think critically about the Israel-Palestinian conflict. Students on campus have formed a group, the Committee to Defend Academic Freedom at UCSB, which is chronicling the saga on its website.
