Hoffman vs Rubin Debate - The Legacy of Two Hippies - History of Rock n Roll as a Social Movement 

Made infamous in their roles during the DNC Riot of '68, and the subsequent Chicago 8 Trial, the legacy of Abbie Hoffman and Jerry Rubin echoes into the modern ethos of the Political Left. By the 1980's, a rift developed between Hoffman and Rubin. Hoffman remained the "Eternal Stalwart Hippie," whilst a more reflective Rubin "softened and evolved" into a more marketable "Yuppie Hippie." This angered many of Rubin's Hippie compatriots from the '60's, including Hoffman. As a result, this led to the Hoffman vs. Rubin Debates of the late '80's (see video summary here).
This Hoffman vs. Rubin Rift still remains within the Political Left today. It was recently made manifest in the 2016 election, as the Democrat Party split into two camps. Some Democrats demanded that the "Rubin - Clinton Camp" lead the party, whilst other Democrats cried foul and demanded that the "Hoffman - Bernie Sanders Camp" represent the Party during the 2016 election. As the grand children of the Hippie - Yuppie Boomers come of age, the question still remains - whose legacy will win out amongst the Political Left? Will the Zoomers that opt to follow the ethos of the Political Left choose the Legacy of Hoffman or will they choose the Legacy of Rubin? Time will only tell.
