I'm not sure what to do about this- how to relate to people whose single minded obsession with politics has tinted every aspect of their lives and thoughts, and they think people that don't see it that way are complicit with their "evil enemies." It's becoming more and more common, and awful. I see this a lot- my family can't even have holiday get togethers anymore, because people that used to get along great have now "joined opposite sides" and can't talk or think about anything else anymore. They'll start lecturing each other loudly, and literally can't think or listen to other people anymore. They do this even if everyone present agrees with them! What is actually happening is the opposite of what they seem think- it's not the other people that are checked out of real life and not taking a stand on things that are actually important-- it is them. Obsessively and angrily watching news doesn't solve problems, nor does blind application of any ideology. Ranting at people with your ears and mind shut down doesn't convince anyone of anything. A simple minded obsession like that can't exist in a healthy person that is actually engaged with the things they care about, and have personal control over. They're not good parents, family members, employees, or community members anymore - the kind of people engaged with making the world better through direct actions - but angry closed minded zealots. I'd like to help these people become human again, and stop obsessing over politics in a way that dehumanizes anyone that doesn't perfectly agree with them. My thought is that it is an emotional problem, and not about the politics at all. They seem to be projecting their own personal anxieties and fears into a political framework, as a distraction from understanding and dealing with them. Or conversely, politics has found a way to weaponize personal emotional problems as a way to engage supporters.
