For those of you with lives, let me recap: Jon Chait wrote a post praising a Michael Kinsley column that criticized a Greg Mankiw column about marginal tax rates and placed on it the headline, "Kinsley Curb Stomps Mankiw." This caused Megan McArdle to criticize Chait for violent language, which caused Chait to apologize, sort of. Sullivan weighed in by linking to a Kevin Drum post discussing the use of harsh language on the Interwebs. And so on.
Ordinarily I would side with Chait in this, on the general principle that most bloggers and columnists aren't actually violent and their use of violent imagery is often sardonic, but in this case Chait could easily be misinterpreted as writing literally, because Kinsley is the most violent person I know. Here is a photograph I took of him outside his house last night:
