Basically, what it comes down to is: In my heart of hearts, I just don't believe that a revolution will happen in my lifetime, even if I live to be an old-ass man.
So if I were to just go all-in on hoping for revolution as opposed to anything electoralism-related, in my brain, I'd pretty much be admitting to myself that I personally won't live to see anything get really significantly better, that when I die everything's still gonna suck or be even worse than when I was born.
And I guess I just can't bear to admit that to myself.
I'm counting the American Revolution and Civil War as well. For bonus points there was also the Glorious Revolution back across the pond in 1688, but I don't know what standing effects that had on the colonies.
Um, a lot, a few revolts, the beginning of the Stuart emigration that peaked after the '45 etc.
