I was thinking the same thing. Weren't their parents and grandparents in the audience? Didn't anybody have any manners? And if they hated him so much, why did they ask him to speak in the first place?
I am a current student at the New School. I was shocked and appalled by the behavior of the students and professors at Graduation. It made them look like idiots. It should be noted that Bob Kerrey basically called them cowards at the end. I am a liberal, and one of the draws of the New School for me was that it didn't strike me as a knee-jerk liberal school. I thought it was more intelligent than that, and promoted tolerance and interest in all view points. That is what I have encountered in classes, at least. Many of my classes have retired professionals as students. I have always thought a sign of good manners was respect for the elderly, and I have certainly witnessed that in the classes I took. (Unlike many of my fellow twenty-somethings outside the university.) That is why I was so suprised that the graduation was so ugly, even though I knew some students were angry about him being chosen to speak. Apparently it was an administrative decision, no students were involved.
