The point is that revolution is necessary
It's been necessary for decades... But revolution is a bloody nightmare that lays the groundwork for rebuilding. You are still going to need a government after the revolution and I'm yet to see any actual tangible plan for what that is that somehow precludes voting right now... It's literally a form you fill out once or twice every four years.
At the risk of painting with too broad a brush, does this rhetoric not means that a lot of leftists have got one foot in the past looking at historic revolutions and one foot in the future dreaming of a revolution to come? And what do you think that means they're doing to the present?
