that seems to be about all the ones I think of which qualify for me thinking someone is an idiot.

To clarify, my issue here is when I have an argument based primarily on hard evidence (such as evolution, global warming, or what certain historical documents litterally say).
The emphases of "hard evidence" suggests something along the lines of "My evidence is better then your evidence. So there!" when all it really means is you value what you consider evidence over what the other person considered evidence. Evidence has subjective value and there are no guaranties that the other person values the evidence as much as you do. Which could lead to argueing over the reliability of the evidence to countless depth with no mutual conclutions other then agreeing to disagree. Even if the evidence is mutually agreeable theres still room for disagreement in interpretation which can lead to argueing to countless depth with each believing themself to know the correct interpretation againing leading to only being able to mutually agree to disagree.
The person may believe that they not you have the upperhand but think theres no way there going to convence you and that continueing to argue isn't going to get anywhere and suggest agreeing to disagree in an attempt to end the arguement in such a way as your both still on talking terms.
I think the repetativenes of there answer suggests someone whose an auditory learner whoam is trying to explain by the same way that they learn. Understanding through repetition. That or perhaps they think the answer makes perfect since and cannot think of a better way to get there point across because they have no idea why you don't get and your not getting it makes obsolutely no sense to them. "Obvious Syndrome" if you will.

But what annoys me more than most is being shouted at or spoken to rudely. It makes me cry and likely to either withdraw or retaliate.
