agreed. I have voted Democrat for a long time, but I can't stand how partisan it's become. The comments are always so low-effort too. The top voted comment in almost any thread will be something like, "fuck trump".
Some people mistake catharsis for activism. It burns a lot of energy while not leading to any progress, or even to building a foundation for making progress.
It almost gives me an uncanny valley feeling. There's a certain pattern to every comments thread that makes me feel like I'm watching a 'conversation' between lazy teenagers, vote-manipulation bots and a handful of (paid?) adult political activists. (I know that sounds paranoid, but fwiw if I were an American I would vote Democrat, and if you applied a hundred randomly-chosen negative adjectives to Trump I would strongly agree with most of them. So this isn't a shocked reaction to seeing an echo chamber populated by the wrong team.)
