Over on Nick Farrell's blog an anonymous commenter wrote the following (which I thought was interesting enough to repost):
Soror SD wrote: "Anyone who talks about Golden Dawn or SRIA as being 'Satanic' has immediately lost any debate they attempt to raise."
This reminds me of Godwin's Law, the internet concept that "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1." (source: Wikipedia). More relevant is the corollary to Godwin's Law (often considered the law itself), that "once such a comparison is made, the thread is finished and whoever mentioned the Nazis has automatically lost whatever debate was in progress." (source: Wikipedia)
I therefore propose Griffin's Law: "When a claim is made that someone is a Satanist, the thread is finished and whoever accused the other of Satanism has automatically lost whatever debate was in progress."
I would also propose the Law of Griffin Dementia: "Whenever a claim is made without documentation that some individual or group has made death threats or put out a hit on a poster or blogger, the thread is finished and the person making the claim is to be banished with laughter."
