What many of these posts show is the Death of Compromise. In my opinion, successful outcomes from politicians depend on them creating the compromises necessary to address issues and keep all of us working together (or at least not killing each other). But we see the unravelling of compromise throughout the society. So that we have the extremists in politics seizing the conversation should not be surprising. And I actually think that the Mods are pretty tolerant here and have a good job dealing with all of us.
The death of diplomacy preceded it. Countries used to make deals that recognized each others interests, allowing for the fact that other nations were allowed to have their own interests.
But that whole notion was strangled to death in the "peace" that followed the end of the cold war, by those who wanted to dictate a unipolar world order. "It turned into We get everything we want, and anyone who wants something else should just get out of our way before they get hurt."
The result was not the acceptance of that world order, but instead a world of escalating connivance and aggression. The public basically just ignored this, believing only different flavours of what they were told to believe, accepting things that in the past they would have questioned or even rejected as going too far.
Compromise died out there in the world of international politics, and domestic politics in "democracies" (and increasingly hollow term) got ever creepier because at the behest of powerful oligarchs, the techniques of tradecraft & war-fighting got applied to the domestic political scene. That led to a public who have bought into the idea that aggressive ignorance can just be substituted for facts, and which has dismissed the possibility that they might be getting manipulated into acting as a weapon for the very people who swindle & harm them.
Yeah, compromise, RIP. Along with so many other principles, rotting in some mass grave which society dug for itself.
