Godwin's Law

Some guy Godwin invented this law, which is comedy & yet so true

"As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one"

Also a FAQ about the law.

I would modestly suggest that the law could be extended, to some type of logarithmic Richter scale type construct, where a Nazi label would get an extreme maximum 10 rating, but along the way other various ad hominem insults such as

stan
gay (and all derogatory synonyms)
douche-bag

would be incorporated on the "Godwin scale".

Perhaps this could be a research project that someone could take up, consider this post as free consulting.
