It seems that Prof. Andrei Serban does not know much about the history of Columbia University. Its been a hotbed incubator of communism since the 1920s.
My grandfather did not allow his daughter to attend Columbia in 1936 because he said it was full of communists. He fled Commies n Europe to come to USA.
You beat me to it. LOL. As soon as I read the story I thought to myself: Typical clueless Ivy League academic.
