I also entirely stopped using Reddit for the same reason. IMHO it's even more toxic than Twitter.
And don't get me started about Facebook. What is it about politics that takes relatively sane friendly people who you've known for years and transforms them into raging psychopaths? When my own sister found out I didn't think Trump was a literal Nazi, she then proceeded to call me a racist, with all her douchebag "online friends" cheering her on. And before Facebook, we used to get along really well. But now it's like Invasion of the Bodysnatchers.
