William I. Robinson, a professor of sociology at UC Santa Barbara, probably shouldn't have been surprised when he found himself in the news earlier this month. He had, after all, forwarded an e-mail to his students that juxtaposed images of Palestinians caught up in Israel's recent Gaza Strip offensive with Jewish victims of the Nazis. The e-mail included graphic photographs of dead Jewish children from the 1940s alongside similar photos from Gaza. In a cover note, Robinson called the images "parallel" and compared Gaza to the Warsaw Ghetto.
