Godwin's Law and Reductio ad Hitlerum
Godwin's law, or the rule of nazi analogy is:
"As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one."
I would argue that this is pretty accurate- I'm sure we've all been in debates when someone points out- "yeah well that's what happened with Hitler and look what he did!" Godwin urged people to restrict their use of Hitler analogies however saying that using it too often would rob them of their impact...
However, are Nazi analogies a fair form of debating? Say in this example:
Person A: "I think that the President should be given unlimited power to pass laws unrestricted."
Person B: "That's what Hitler got...and look what happened with him"
Is this a fair point?
What about this one?
Person A: "I think hunting animals should be banned."
Person B: "Hitler banned animal hunting, therefore you are a Nazi"
OK, obviously the second one is hardly logical- it's an example of the Reductio ad Hitlerum fallacy in debating, simply association with Hitler to discredit an opponents points no matter how loose the association is.
However, are the Hitler analogies always invalid? Can anyone think of any good examples of Godwin's Law in action?
Discuss.
[edit] A more contentious example might be needed. A person might say Barack Obama is popular, an excellent orator and charismatic therefore he is worthy being voted for. Another person might respond, Hitler was all those things too. Is this an invalid point? Or is it actually a good one: just because someone is popular, a good orator and charismatic doesn't mean they are a good person. The bringing up of Hitler in this case isn't an attempt to suggest Obama is a Nazi but just to demonstrate how certain qualities can be shared by both good and bad people... however, is because of what Hitler did, it unfair to even mention him in comparison with someone like Obama?
