I found politics to be too pervasive to escape on Reddit, which is why I eventually deleted my account. I tried to stick to non-political subreddits, but when I found myself reading comments about police brutality in r/dogswithjobs, I knew I no longer wanted to use the site.
What's sad is the political discussions aren't even good. Comments are written to appeal to the lowest common denominator of reader, and a lot of subreddit comment sections move at breakneck speed, so what you end up with is a bunch of politically like-minded people dogpiling on top of each other to write something like "Being a republican at this point is basically saying you agree with killing the planet" (an actual current top comment on r/news right now). A few comments down in the chain will be a Futurama reference.
