We seriously need to start pushing back on this Divided America Trope. It is absolute propaganda.
America is more divided than ever.
Wrong. there are a lot of antisocial criminal elements in a America. Though the problems do get more aggravated, there are far fewer violent crimes, political or otherwise per capita than ever before
The American Congress is frozen by Partisanship.
At least mostly true. But it doesn't really represent as new state of affairs, it least not in the last decade or so.
We're headed for a civil war
Maybe; there certainly seems to be an element that wants one, and a revolution in government. But they have proven to be a relatively tiny, if startling, sliver of of the population, the military, and the police. At least, when the chips came down.
I think that this is a media narrative that feeds on itself in two ways. The first being that it is an insidious 'both sides' framing of the state of affairs. The Democratic party is not just another flavor of political party; the GOP Republicans are not just another flavor of political party. The fact is, the Republican party can be shown to be composed of two basic types of people: those being charged with felonies, and those trying to protect or defend them from those charges, often becoming tainted with their crimes.
The democratic party is the other half of a previously functional government (I'm being generous here) that has been left holding the bag while the other party turns to crime, conspiracy, and the craft of procedural sabotage.
This has all been predicated on the moral tenets of a religion that they neither understand nor practice, and that has opened the door to nationalist authoritarianism and outright fascism as they have been emboldened and supported by the most most crass and self serving of the evangelical 'personality' churches out there.
In Canada we get a lot of similar discourse around division. Usually it is convincing folks that "the Liberals hate you and want to make your life hard and think you are the worst and are diving the country". If you don't actually engage constructively with the other side of the political spectrum, it is easy to be convinced that you are are some kind of victim. The so-called division is being whipped up by the very elements that decry it.
