After the lecture, attendees filed out of the hall to discover that the protesters had massed so as to allow only a narrow passage between themselves and a retaining wall. In effect, all those leaving the lecture were forced to walk a gauntlet. Some ducked their heads, others set their jaws in anger, squeezing past the dozens of assembled faces chanting "Shame! Shame! Shame!" as fists pumped the air in unison.

A young woman in a kaffiyeh screamed up at a Jewish student significantly larger than herself. Her lips were wet with fury. "If I don't agree with you, then you call it anti-Semitism!" she shouted, as friends arrived to support her. The young man was surrounded. "You call it anti-Semitismmm!" she raged. "Why can't you tolerate anti-Semitismmm?"

"I can tolerate it," the student replied, his voice a low, tired rumble. "I have to. It exists. I just don't have to like it."
