Do We Like Personal Attacks or What?

I was going over the 50+ posts I've made to The Serenity of Reason and I noticed a pattern. It seems like the most commented-upon posts are the ones that start as personal attacks. That would be the Ben Stein post and the Chuck Norris post.

I wonder if that is because people want to come to the rescue of the attacked? Or is it because we want to pile on? Probably a tad more of the latter than the former if you read the comments, but there is a smattering of both.

I suppose I'll have to find another asshole to attack if I want to rile up the troops into commenting... any suggestions?
