columnbia and berkeley were the chief schools through which the Frankfurt school made their entrance into the USA.
the frankfurt school taught that western civilization needed to be destroyed from within in order to create a communist state. their methodology for doing so was critical theory. one of their acolites in secondary education for example was howard zinn.
the reason that communists and jihhadists marched together in the early days of the iraq war was that both wanted the destruction of western civilization. only communists wanted a communist state to replace it. the jihhadists wanted and islamic state to replace it.
this is the reason that columbia acceptd edward said when I was there. He was in favor of americas destruction as constituted as much as the communists in power. they didn’t quibble as to details of what came after.
I was at columbia when obama was there. his political views were shaped by his days at columbia.
In '68, when the COLUMBIA RIOTS took place, it wasn't due to a predominance of lefty profs, but rather, because of damned RED DIAPER BABY SCUM students! Unlike you, I was alive, an adult, and living in Manhattan at that time and knows ALL about that. My assumptions ( well educated guess ), in '68, were all proven to be 100% true, years later, by David Horowitz and then, much later, by other books written by ex-Weathermen and/or SDSers.
It was jelly spined profs and the then president of Columbia, that allowed the SCUM to get away with what was done, back then.
And wee barry's political opinions were FORGED IN THE WOMB; he was raised/trained to be what he is, AT HOME, long, loooooooooooooooong before he ever got himself to Columbia and NYC!
