Enter The Dragon Puns

I have come to the conclusion that the reason for trolls causing flame wars is a direct result of Dungeons and Dragons.

See, in dungeons and Dragons, the only way to kill a troll is with fire and acid. So when a troll enters a forum thread, the flame war that erupts is an attempt to kill the troll with fire.

I suppose an acid war could also erupt, but those who would use acid seem too stoned to care.
