Mann became involved with Students for a Democratic Society (SDS) in 1964 and became the coordinator for New England. In 1968, he helped lead massive student protests at Columbia University. The Columbia Student Revolt brought the SDS instant fame. The Students for a Democratic Society fractured in 1969 and the radical Maoist wing led by Bernadine Dohrn and Bill Ayers purged the Moscow-supported CPUSA elements, complaining the SDS wasn't radical enough. They pushed for more violent direct action than simply protesting.
Inspired by their communist heroes Fidel Castro, Che Guevara, and Ho Chi Minh, the SDS said a people's revolution could succeed in the United States. The shock troops that white SDS Maoists wanted to enlist as the spearhead of a National Liberation Movement, patterned after the Viet Cong, were the Black Panthers.
Black Lives Matter (BLM) co-founder Patrisse Cullors is a "trained Marxist" who was trained by Mann. BLM is a fundraising scheme of the Democratic National Committee advocating communist revolution.
As of 2016 Mann was running another Liberation Road front, the Labor/Community Strategy Center. Like many professional leftists, pocketing over $225,000 a year in “the system” he advocates destroying.
