And that's an overwhelmingly good thing. The nut jobs and extremists are looking for an excuse to start shit but (as you correctly stated) lack the resolve to finish shit. They want to do a little political violence to feel enfranchised and like they have some control, but they're not ready to give up everything for a cause. This makes them particularly dangerous.

The real bulwark against government fuckery is the people you don't hear about: normal folks who happen to have guns. It would take actual, serious grievances against large swathes of the population to make them do something. Because that much larger (and more ideologically diverse) cohort isn't champing at the but for a fight they haven't lied to themselves about being able to maintain a normal life and therefore wouldn't start one lightly. That's pretty boring, so you only hear about the weirdos.
