Columbia University was one of the Ivy League/East Coast leading universities targeted for infiltration by the Communist Party and other Marxists since the 1930’s.
Over the decades they managed to get their people in as professors (i.e. Prof. Corliss Lamont, late head of the Philosophy Dept, id. CPUSA member and financial angle and Soviet propagandist - had a Chair named after him), then the SDS of the late 1960’s where the administration caved into the red mobs (Mark Rudd, Steve Halliwell, etc), and now it has become a leading bastion of Moslem anti-Semitism and anti-Israel propaganda and subversion.
Instead of singing “Hail Columbia”, they are now singing the communist “Internationale” and “Halal Columbia”.
And many of the other NYC schools are just as bad, NYU, CUNY, John Jay College, etc.
The Working Family Party, which essentially runs NYC government right now was created at Columbia University.
