Read Street was a lively place for commenters last week, in the wake of President Obama's Nobel Peace Prize. And "lively" is an understatement. The comments were unusually vitriolic and polarized for this blog. They put me in the unusual role of censor, so I thought I should explain my thinking on the topic.

Comments must be approved by me or Nancy before they're posted on Read Street, and I'm usually pretty light-handed, killing only those that are obscene or slanderous. And the bounds of fair comment are broad when a political figure is the target. So I posted many harsh comments, even though there was obvious irony in those that said Obama's Nobel was premature, while skewering him for a host of political sins that he could not possibly have had time to commit in less than a year in office.

I admit to censoring one comment though. It was from a Holocaust denier. That, to me, was in its own way, obscene and slanderous to the memory of all who died, and all who remember them today.
