And in my humble experience, some significant part of the left has increasingly turned to dogmatic absolutism in recent years, maybe under influence of social media. I'm far from a centrist (would consider myself fairly radically left wing in many aspects) but I've been called a bootlicking scumbag for saying something like "not every single police officer is the absolute scum of the earth."

I've always held that one of the key parts of what sets us apart from the right wing is that we allow questioning our own beliefs and are open to nuance. But that seems to be less and less the case.
