I had this professor last year.
Yes and No.
He's got mental and emotional problems which hamper him.
If you say something that disrupts he view of reality, he gets emotional (or as others put it "ecentric").
Saying Krugman served on the advisory board of Enron makes him go ballistic, he calls it all lies, even if its on Krugmans own website, he sort of called Krugman wrong (or liar, your pick) in trying to defend him.
He does not need censure, he needs therapy, I told the director of the program this, and most of Yoshi's collegues answer with the usual "ah, he's harmless" and "excentric" explanations.
