I'm unimpressed. The US has crushed rebellions from its inception, famously including the civil war but also many other attempts, and I would say that the patterns of what some call the New Afrikan nation within the US to revolt, going solidly up to the 1980s or further depending on your interpretation, are perhaps the most important.

As some guy said, "Revolution is not a dinner party" and establishing and maintaining a revolutionary state requires its own violence. No Marxist says otherwise, as it is the famous quote of Engels: "The proletariat uses the State not in the interests of freedom but in order to hold down its adversaries, and as soon as it becomes possible to speak of freedom the State as such ceases to exist."
