>My point is that's pretty much all arguments, except maybe some very obtuse ones no one really cares about.

There is a distinct difference between a person having emotions while arguing, and using an appeal to emotion as a rhetorical tactic. I do not agree that "pretty much all arguments" contain an appeal to emotion (again, as a purposeful fallacious rhetorical tactic), even though all arguments obviously will have people feeling some sort of emotion.

Even looking through this entire thread, most of the disagreements here do not contain appeals to emotions.

I'm sure that any book on logic and rhetoric from the last few centuries would explain it better than I can. The wiki page has some good explanations and examples as well.
