I would not say I have a completely thorough understanding of Marxism, but this video definitely represents the most secular / collectivist mentality I have ever seen in America. The closest thing I can imagine as I watch this video is Jim Jones and his followers at Jonestown, or David Koresh and his followers at Waco.
From the YouTube description:
What we saw at the "revolution":
Many curious citizens and media outlets came to the first Occupy Atlanta event, and were visible shocked and confused by the consistent Marxism employed by the group. People abandoned their individuality and liberty to be absorbed into a hypnotizing collective. The facilitator made it clear that he was not a "leader" and that everyone was completely equal; words often spoken by leftists, but in this case they actually applied their philosophy. Into this surreal and oppressive environment, Rep. John Lewis, a civil rights hero and icon of American leftism, came to speak as has so often done at left-wing rallies and events in Atlanta. He is practically worshiped in Democrat circles, and was visibly stunned to see these Marxists turn him away. It was reminiscent of previous Marxist revolutions in history when those who ignorantly supported the revolutionaries are, over time, purged and rejected for the "good of the collective", when their usefulness has expired.
