I guess you haven't been following US politics for the past decade or so.
Major changes have been taking place in how the media behaves, different portions of society behave, along with how the political elite behaves. All of which has culminated in today's events. The ones who had near to complete control over the political narrative and opinion doubled-down on controlling it, and ousted all wrong-thinkers as "radicals" or "conspiracy theorists."
It became normal for the establishment to spin endless lies, do so in a unified voice, and avoid accountability for doing so.
The problem I saw in all of this, was that all of these idiots got drunk on power to the point of not just ignoring the opinion of the US population, but actually convincing themselves that the opinion of the US population doesn't even exist. Alienation between the top and the bottom became too toxic, people became angry, and after the election fraud (and say whatever you want about whether it happened or not, but to my amateur eyes the elections looked very dirty), the top refused to do anything to reassure the public, by tossing investigations out the window. The establishment felt like it didn't owe anything to the people at all. Things were snowballing for quite many years now. I was just waiting for it to burst.
But there will still be morons singing songs that everything is fine in the US, and "right-wing nutjobs" are destroying "paradise".
