The main thing about /r/politics that I have only recently noticed (since the 2016 election) is that they have become extremely orthodox democrats. Before that election, a lot of the time they were a mixture of libertarian and farther left leaning (but certainly not orthodox) people. Now they focus all of their time on Trump bashing, which isn't bad per se, but is extremely annoying since it's pretty much the only thing the sub is about these days. Thing is, there are a lot more political things going on than Trump, and outrage culture has resulted in at least two WaPo posts over each and every one of his tweets.

And then in the comments, you'll be crucified by the posters for anything other than the pro corporatist democratic views that the posters espouse. Move on from bashing Trump to say, bashing Hillary because she was an utterly unlikable candidate and arguably the biggest political failure in modern history, and you draw the ire of dozens of toe-the-liners who see the world just as black-and-white as the idiot /r/the_donald posters.

There's also an excessive amount of hyperbole that just gets annoying as time goes on. Clearly Trump will be around for quite a while longer (until and unless Mueller finds a smoking gun or in the event of a massive Democrat success in 2018), but reading /r/politics you would think he'll be impeached by next week. Adding fuel to the flames are websites like WaPo and the Independent who publish articles with these terribly misleading and hyperbolic headlines that make it seem like Trump is going down, and you get a massive echo chamber fueled and funded by shitty media websites.
