It took 30 years between Lenin's brother being executed by the state, and the Russian revolution. History has momentum, and the gains from the New Deal are still enough that many Americans dont feel comfortable putting their bodies on the line. People's dispositions are a function of their material reality and the reality is that most people haven't internalized the damage yet.
Also Americans have always allowed government over reach and corruption on the assumption that the AR-15 they have a pretty good grouping on at weekends is what'll solve the problem if it gets "really bad".
I call it the violence event horizon: a whole lot of people's critical thinking just stops, as though an actual war will make things so much simpler.
As I look at it, rhetorically, when is the point for a US citizen where taking up arms against the US government seems less dangerous than business as usual? I’d say it’s still quite a ways off for most.
