His temper with feedback is extremely short. He seems to get very angry very quickly with people who challenge him on anything. I usually don't find him to be wrong on his actual facts, but I do find him to be pretty wrong on his tactics and the way he deals with people who do not agree with him.
That's the one big criticism I have of Dillahunty. I can understand the frustration of hearing the same BS over and over, but that doesn't justify acting like a douchebag.
