There are many corollaries to Godwin's law, some considered more canonical (by being adopted by Godwin himself) than others. For example, there is a tradition in many newsgroups and other Internet discussion forums that once such a comparison is made, the thread is finished and whoever mentioned the Nazis has automatically lost whatever debate was in progress.
I propose a new law. It's called Paladin's Law and it asserts that in any modern discussion where one side is compared to Terrorists - even though the comparison is ridiculous - the side making that assertion automatically looses the argument.
