If you want true Hatfield vs. McCoy action, go to the Road forum and throw down with a little "Lance Is a Cheater" and a bit of "Campy pwns Shimano". I lurk, yet dare not post... The Mountain Biking forum has some real tight-asses too, but pretty much everything pales in comparison to the catfights in A&S. The Commuting forum is pretty civilized, other than the Rivendell threads.
