I can empathize this, but I think that limited human mental and emotional bandwidth requires some kind of compartmentalization. If I am trying to do my day job and can't avoid getting drawn into political debates, that's exhausting. If I share an interesting article about new Javascript features, it doesn't mean I'm either endorsing or ready to debate the author's climate-change-denial posts from years back: that's also exhausting. If I go to read fan theories of my favorite books, only to have the conversations focus on the author's controversial Tweets du jour, that's exhausting. If I'm watching the Superbowl, and everyone keeps interrupting the game to tell me how awful a person one of the key players is, that's exhausting. Granted, I do think you're totally right that there are places to discuss these things, and I don't know of a one-size-fits-all approach here. That said, the "don't-let-my-peas-touch-my-mashed-potatoes" (new phrase for me, and I love it) instinct is quite reasonable, since otherwise life becomes an infinite stew of pessimism and critique.
