That's fair. It's definitely possible to go too far with this. I guess what I want to argue is more like this: The problem here is sufficiently hard that, even though we can make definitive judgments about facts and misinformation in some cases, the value of doing so in practice will be low. But of course that's a pretty vague blanket statement that I'm making without any concrete support, and it would probably be better to look at the pros and cons of some specific idea about what the rules should be.
