Oh pul-eeze. This is not news. For 60 or 70 years, Bank Street has been an open-air experiment for movement Communists to abuse their children with boring, insane doctrine for the sake of the same 19th-century ideological fashions. They've been selling this particular line since the 1960s at least. Any curriculum change described here is a nuance.
P.S. Bank Street is in Greenwich Village.
