I was not aware how many of these cancellations have been piling up:
Haverford College on Tuesday joined a growing list of schools to lose commencement speakers to protests from the left, when Robert J. Birgeneau, a former chancellor at the University of California, Berkeley, withdrew from this weekend’s event.
Some students and faculty members at Haverford, a liberal arts college near Philadelphia, objected to the invitation to Mr. Birgeneau to speak and receive an honorary degree because, under him, the University of California police used batons to break up an Occupy protest in 2011. He first stated his support for the police, and then a few days later, saying that he was disturbed by videos of the confrontation, ordered an investigation.
Those at Haverford who objected to his being honored asked Mr. Birgeneau to apologize and to meet a list of demands, including leading an effort to train campus security forces in handling protests better; he refused.
Mr. Birgeneau bowed out a day after Smith College said that Christine Lagarde, head of the International Monetary Fund, had withdrawn from its commencement because of protests. Condoleezza Rice, the former secretary of state, said this month she would not deliver the address at Rutgers University after the invitation drew objections. Last month, Brandeis University rescinded an invitation to Ayaan Hirsi Ali, the Somali-born activist, over her criticism of Islam.
The story is here. I have nothing to add to the obvious points here, but this is nonetheless worth emphasizing.
