Godwin's law

I see a lot of "pulling Godwin's law" in my future, so I'm going to do some clarification on exactly what that means.
When I pull Godwin's law that means that somebody used the argument "The Nazis (...) so therefore (...)" Same goes for Hitler, Al Qaeda, Stalin, Lenin, Marx, Mao etc. I'll even extend it to "Jesus". And the argument I make is this: Just because someone liked or disliked something does not mean that thing is automatically good or bad; and if you make such an absurd claim you automatically lost your credibility in the conversation.
When I pull a Reverse Godwins law, that means I'm using a Godwin's Law analogy to show that your argument is absurd; usually by injecting the Nazi's or Hitler into your argument. For instance: Hitler probably won a lot of debates; killing jews is still bad and winning a debate is not evidence of truth.
