An anonymous commenter on my Krugman-in-Wonderland post today (in which I take on Krugman and his romantic view of state-run rail service) writes the following. Oh, it is classic:

Mr. Krugman and trains… I took a train from D.C. to Boston this summer. On the way back, right around Baltimore, I looked up and there was Paul Krugman. Well I happened to be reading Murray Rothbard’s “America’s Great Depression” on the train, and couldn’t help but laugh. After I explained to my girlfriend what was so funny, she decided to take the book up to Mr. Krugman and get him to sign it. I don’t know if he would have done it under normal circumstances, but my girlfriend is a 10 on anybody’s hotness meter, so men rarely tell her no. What was so interesting is that he told her, “your boyfriend shouldn’t read this book.” Not, “he shouldn’t believe everything in this book,” or “everything in this book is a lie,” but instead “you should not read this book.” Who thinks like that??? That you shouldn’t read any books that challenge your views, only things that confirm it. And this was coming from a man that is in charge of teaching the future of America at one of our best institutions of learning.
