Intolerance in Academia Makes it Intellectually Weak

Yesterday I reviewed comments on an Upshot article "Presidential Campaign Myths on The Economy" by N. Gregory Mankiw that seem to skew very contrary to the article's point because the author was described as Conservative.  It was interesting because I came upon the article from Robert Reich's tweet where he agreed with its conclusions and which comes to the point on Nicholas Kristof's "Confessions of Liberal Intolerance" in academia. I congratulate Robert Reich, an economist best described as a Liberal, for agreeing with a Conservative making a rational argument. It gives him credibility as a fair judge.  Intolerance of every argument from the other side makes your viewpoint weak, wherever you are coming from.
