Kenneth Waltzer and Mark G. Yudolf: The most ludicrous claim by Franke is that anti-Israel advocates on campuses are being disrupted and “purged.” There is virtually no example of an anti-Israel speaker being silenced by protesters. Criticized, yes, but not silenced. Katherine Franke: I imagine that Swarthmore Professor of Peace Studies Sa’ed Atshan would disagree. A speech he was invited to give at a Quaker school in Philadelphia was cancelled after some Jewish parents objected to his views on Israel. Not only that, the teachers who invited him were fired.
