Jesus. It'll likely only get worse after the midterms too...
It doesn't help that the ads are literally calling this "The vote for America's future"; they're building this election up to be the apocalyptic war over the direction of the country for all-time. (As if the country won't just change directions with each presidential election the way it nearly always does). This partisanship is reaching an unsustainable fever-pitch, and bringing out the crazies... or perhaps they aren't crazy. They're just the only ones talking the insanity of our current political discourse to its logical conclusion; if there's no point in dialogue or discourse and the other side is purely evil, then shutting them up my any means possible is the only 'rational' course of action.
That insane proposition is basically the future we're building for ourselves; the outgrowth of this incessant vilifying and vitriol. And, yeah- sadly, while the left wages its wars with words and walkouts, the right tends to contain all the firearm enthusiasts. So, when the left-extremist come out, they go Orwellian... but when the right-extremists come out, they go Kaczynski.*
Either way, we have to find a way to stop feeding the cultural trolls; to get the extremists to go back to their hidey-holes and shadows, instead of sounding the battle-cry that has each of them spurred to action. Politics in America can't be war anymore, because this war is producing actual soldiers and actual casualties.
We need to find a way to talk to each-other again. And we need it badly.
*Also, I got my names mixed up; I googled 'McVeigh,' found out I had the wrong historical figure, and googled 'unabomber' immediately after that to get the right name, so I am guaranteed on some FBI watch-list now...
