Marcus Plieninger, a former graduate student at Columbia, tells tales out of school.

In a letter to The New York Sun, he recalls one of his teachers, a “Professor Anderson,” compared President Bush to Hitler when Plieninger “asked him why it took the Jews so long to leave Nazi Germany.”

Another, a “Professor Huyssen,” proclaimed “Pope Benedict XVI a ‘bad man,’ compared him to East German Marxists, railed against Fox News, and suggested September 11 is important also because it is Marxist philosopher Theodor Adorno’s birthday.”

Plus ça change.
