I wish there were anywhere that adults could talk about interesting stuff intelligently without a thousand stupid and/or I've-already-thought-about-this-and-the-basic-talking-points-aren't-going-to-change-my-mind arguments taking up 99% of the space.

I feel like maybe the answer is browser-integrated LLM plugins tasked with "I don't ever want to see anything having to do with this topic of argument ever again."
