I’ll add a third reason, which is I think in general, people are very bad at understanding how to make an argument to someone with a different value system. I’m liberal, I have family members who are conservative, and I’ll read conservative books and I’m genuinely a person who is curious to new ideas, but most people I know(and I’m sure this works vice versa) are only good at expressing political opinions in the language of people who share their values. Republicans and Democrats don’t just talk about different things, they talk about them in very different ways.

I find this online as well, like I hate being “out of my echo chamber” because those arguments are just uniformly pointless. (This is in all directions by the way, people to the right or left of me).

Though I also interestingly find trying to talk to LLMs about competing values challenging too, if I try to get the LLM to explain a conservative position, then I make counter-arguments to that position, it will almost never tell me my counter argument is wrong, just “you’ve hit the nail on the head! Boy are you smart!”
