Well, “stupid” in the broad sense (as in “all humans are stupid, not “muggles who haven’t been Enlighthented By Saint Eliezer are stupid”) - if two people have different information and come to different conclusions, and notice they disagree, they should still be able to try to share that information see if it makes them closer, rather than going “OMG you must be evil!!!”.
Another is that people have different information, which leads them to different conclusions. You don’t need to be stupid to be wrong.
