I don't disagree with you, but it actually seems like a great strategy to avoid internet arguments... My grandfather used to tell a story about how when he was a child he'd get beat up on the way home by the bullies on the corner (circa 1950).

He resolved it with a similar approach - run in headfirst, fists flying, clobber everybody before they knew what hit em, and bounce. Seems a good idea to quash the trolls before they even get started.
