I think that David has captured one of the keys to being a dependable voice in the blogosphere as he talks about childish behavior. One of the things that really tells me that a blogger is fair and civil in their discussions is when they can accept comments of disagreement without getting petulant or childish. Deleting comments falls in the class of childish – my policy is to never even consider deleting a comment except for the “comments” left by bots as popularity boosting links to online casino’s and the like; those get deleted and banned.
My viewpoints disagree with the viewpoints of David Anderson somewhat regularly, but he has consistently proven himself to be mature and civil. His thoughts are honestly held and fairly well thought out. For all these reasons he is one of the people I most enjoy reading.
