Query: Hollywood-backed Marxist education

Zinn's objective is not to impart knowledge, but to instigate "change" and nurture a political "counterforce" (an echo of fellow radical academic and Hugo Chavez admirer Bill Ayers' proclamation of education as the "motorforce of revolution.") Teachers are not supposed to teach facts in the school of Zinn. "There is no such thing as pure fact," Zinn asserts. Educators are not supposed to emphasize individual academic achievement. They are supposed to "empower" student collectivism by emphasizing "the role of working people, women, people of color, and organized social movements." School officials are not facilitators of intellectual inquiry, but leaders of "social struggle."
