How does “the majority of history” prove that this specific story is correct?
Or do you just mean, the majority of history proves your ideology correct, which means you now get to make all kinds of unsubstantiated claims without evidence and everyone’s just supposed to believe it?
Every part of our society is dysfunctional and declining, and that’s self-perpetuating. If you throw a rock, you’ll hit a reason why the US is like this. We are pretty FUBAR.
It’s pretty much always been this way, like if you look at opinions and rhetoric post-9/11, the overwhelming majority of people supported Bush and it was common to talk about nuking random countries in the Middle East. Back then we were a bit less mask off in that Bush wasn’t as blunt and explicit about things as Trump is, but the bodies were just as dead. Trump realized that the facade of politeness had become vestigal and didn’t actually matter. As for American liberals, the thing to understand is that they only compare themselves to Republicans and so as long as they are 5% more proper and 5% kinder, 5% more intellectual, etc, they see themselves as having all of those qualities, but from the outside, to someone who has reference points outside of American politics, the differences often seem pretty marginal. So for example, “I can excuse indefinite detention without trial at Guantanamo Bay, but I draw the line at torture” and within the context of American politics that’s reasonable and even left-leaning but in a broader context, it’s like, "You can excuse what?"
