This week, he was disinvited from a regents' dinner at the University of California, where he was going to speak, after a bunch of faculty members protested that his views were too repellent. "I was appalled and stunned that someone like Summers would even be invited to speak to the regents," said biology professor Maureen Stanton, who helped put together a petition drive. "I think many of us who were involved in the protest believed that it wouldn't reflect well on the university that he even received the invitation."

I have in mind statements of fact or policy that are defended with evidence and argument by serious scientists and thinkers but which are felt to challenge the collective decency of an age." ...
