New York Times veteran liberal columnist Nicholas Kristof is usually good for one or two iconoclastic columns a year that make his usual fans petulant and his conservative critics grin. This year the two are on the same subject: Liberal intolerance in academe. His latest column in the Sunday Review is a follow-up to his May 8 surprise, which drew outrage from liberals aghast at the idea that conservative should have a voice in academia, in the name of diversity of thought. On Sunday Kristof confirmed that liberals were prey to the same "cocky...narrow-mindedness" they accuse their conservative opponents of.
