The right is way more hooked into the culture war, but plenty of leftist communities cannibalize each other via “no true Scots”-ing each other with intersectionality. I see very little patience or compassionate education on intersectionality, and instead see a competition about how quickly one can scold. Regardless of whether that’s valid, it sure as hell makes it difficult to build bonds with other groups or onboard new folks to leftist ideas.
It’s worth mourning that someone in the custody of the state isn’t being protected from attack. For every evil cop getting stabbed there’s a ton more people (some of whom are innocent) who are subject to the same negligence and cruelty in the system.
