We had a really good run between World War 2 and 9/11, where we either believed, or were pressured to believe, that some things are more important than partisanship.

Between 9/11 and 2014, we were sorta-kinda holding it together. But by 2015, that run finally ended for good.

That was the era of McCarthyism, then the Kennedy assassination, then Nixon resigning after a massive scandal and inevitable impeachment, etc.

We didn't start the fire, heh.
