The culture is extremely polarized, but we aren't going to get into any sort of situation with widespread anarchy. Some areas could have protests that border on riots, but I don't think they will last. I also don't think they will be that common.
I do think some of this will go away whenever Trump is not in the picture. He is a very, very visible and very, very vocal target for criticism, a lot of which he brings on himself. The left would attack any Republican President, but, unlike pretty much every other President in recent history, Trump will directly and strongly engage. He has absolutely no problem getting on Twitter, getting on the news, making inflammatory comments at a rally, etc.
Of course, all of this triggers the left because they are shocked at the idea that anyone would be as brazen as Trump (regardless of the topic), and they become even more outraged. They are even more shocked that a very large portion of the American people respond positively to Trump, which frustrates them even further.
Trump obviously understands this and continues to play the game because it works well for him politically. Republican politicians go along with it because they have nothing to gain and everything to lose if they oppose him. Besides, they don't want to give up ground to the Democrats, so I think most politicians are just going with it until Trump is out of office.
Unless someone else replaces Trump as a strong personality with a very devoted base (unlikely), I think the GOP will move on but without the Trump-stirred drama. The left won't have as clear of a target for criticism, and the left can retreat into their echo chambers. Sure, some will continue to make noise, but I don't think the average American is on board for the left-wing nonsense being preached today.
I'm not saying that Trump is the cause of this. Rather, he's the agent that brings everything to the surface. Although I don't like the way Trump operates, I do appreciate how he has shed a whole lot of light on what the left truly believes. It has been eye-opening for sure.
