"Everything written by, for, or against Krugman over the past 15 years is a waste of time. That includes this post as well as Adler’s. It includes various attempts by Henderson, Cowen, and Sumner to engage with Krugman. They try to treat him as if he had some sense of decency. Instead, he is Joe McCarthy with a Nobel Prize."
And as pointed out by others, this is on a blog with the subtitle 'Taking the most charitable view of those who disagree'.
I guess this post is also a waste of time.
