I mean...in the 60s and 70s violent crime was at an all-time high, politically-motivated bombings and plane high-jackings were happening, the country was ripping itself apart over the Civil Rights movement, politicians and political activists were being assassinated left and right, the President resigned due to corruption, and
Russia was trying to spark a race war in the US.
If
all of that didn't cause this country to engage in an
actual second Civil War - it ain't happening now. Partisanship will certainly get worse, especially as we inch closer to midterms and especially the 2020 election. Things will definitely get uglier, but at some point (no idea when), I think the country in general will tire of it. This is not our first rodeo.
