They must be fundamentally incapable of processing the fact that they aren't automatically winning forever just because they're on the "right side of history" as declared by themselves. I really have no explanation for the mentality that every fight is an existential one and that you should automatically win it and if you don't well it's all over forever but also time to prepare for the next one which starts immediately. I've tried to figure it out because it's baffling and also technically right in my wheelhouse yet I remain stumped. 2016 was the beginning of their long reign and they lost instead. Then it was a resistance for years where they did nothing. Then BLM escalated and Trump was defeated and yet their guaranteed victory didn't happen again. You'd think these defeats would cause skepticism in the belief that history is on your side and will guarantee your continued victories forever. You'd think the continued completely expected consequences of things would cause them to realize that every moment is not an existential struggle.
Narcissism can't be the only explanation for the "I voted but nothing I care about changed" mentality, especially not for the people who invest themselves into it constantly. It'd make more sense to go "well, I voted but nothing happened" and then you just ignore politics or decide that maybe you'll try Trump this time or split your ticket for the legislature, this is what normies do constantly. Yet they're constantly on a march to the "left" for "democracy" and angry that anyone ever slightly resists them.
I find it interesting from a personal point of view since I'm also an extremist and radical (obviously a better one) yet I've never once considered history to be a ceaseless march of my guaranteed victories. Libertarian circles are pretty much never like this, anarchist ones are far more hit and miss (left ones definitely more in this vein, but many anarchist circles are often predicted on the theory that one symbolic action will overthrow all systems so there's a logic to it) but the "progressives" are always like this. Now the "conservatives" have mainlined so much of this culture that they too are like this. Yet these last two circles are supposed to be the less radical and more moderate entities. Many "centrists" in the media and such are similarly constantly escalating things to the existential level and freaking out about everything too. Maybe it's just a personality type?
I'm not saying I think it's "dangerous" in the way they themselves say about everything, but it's definitely unhealthy not just to the Republic, not just to their own segment of society and culture, but personally. And I have no answers, of course, so perhaps I am even worse than they are for taking notice of it at all.
