This is a useful observation, because I was thinking about these kind of cases especially. Other cases are easier to explain away, but I think we're missing something that this kind of case captures: Why would someone be mad when a definitely wrong person disagrees with them? How is that their problem? I don't think ego or insecurity or any of these typical lay theories explain that at all. Is it just a matter of not getting what one wants, i.e. for there to be less wrong people in the world or something?
Why does the person have an impulse to control in the first place?
