Stupidity Stupor

A state of confusion when a smart person is arguing with an idiot, and the smart person suddenly hits a mental brick wall because the other person is so utterly ignorant, it's shocking that they can even think the way they do and take everything they say 100% seriously.

Paul had a stupidity stupor when he realized Jeff was 100% serious about his belief that the Holocaust was a fake event staged by the Jewish.

(A/N: I did not make this up. There are actually people who believe this.)
