Snipes William A. Jacobson after digesting Krugman's new column. But what Krugman said was: "So let’s not be civil. Instead, let’s have a frank discussion of our differences."
It seems that Krugman is associating civility with affecting agreement when there is and should be none. What's wrong with that? Rush Limbaugh says the same thing on practically every show. Let's speak clearly about the different ideologies and policies so people can see what they are and judge. Don't obfuscate with the pretense of agreement and friendliness.
Do we the people really give a damn whether our representatives in Congress and the state legislatures like each other and get along socially?
