At a Nov. 10 vigil at the University of Southern California in Los Angeles, professor John Strauss made clear his condemnation of the terrorist group that rules the Gaza Strip and attacked Israel on Oct. 7.

“Hamas are murderers; that’s all they are,” he said. “Everyone should be killed, and I hope they all are.”

In response, administrators chose to bar Strauss from campus, allowing him to contact students virtually for the rest of the semester.

“Totally barring a professor from campus because of a passing comment like this is a shocking overreaction. Regardless of professor Strauss’s intent, he is entitled to his views and the right to share them,” said Jonathan Friedman, director of free expression and education programs at PEN America.
