To be more precise, I think that the Godwin's law, as used on the Internet, is stupid.
For those of you who lived in a cave or don't like debating (but the fact that you are among the 20 active users of this message board indicates that you actually like talking for hours with strangers on subjects for which your opinion doesn't really matter), the Godwin's law was developped... long ago.
To sum it up, it's a theory saying that the longer a conversation is lasting, the higher is the probability that someone is going to make a Nazi analogy.
For example, you are discussing abortion. And well... the conversation is reaching 10 pages, someone already said "more salt", and someone says, half jokingly, "I think that some people should be sterilized".
And then someone else answers "HA ! Like Hitler was doing with mentally handicapped people !"
The Godwin point has been reached.
Now, on today's internet, people are using Godwin all the time. At first, it was to dismiss stupid analogies but now, it's used everytime someone mentions Hitler or nazism.
And that's my problem. It's basically an easy way to dismiss someone's opinion eventhough their agument might be relevant and involves nazi analogy. Without any further discussion.
And you see, that's scary because now, when you have a discussion on the Internet and some people might actually be antisemite, racist or assholes in general, and you basically call their bullshit, they invoke the Godwin point.
That's why I hate the Godwin's law, and I think it should be forbidden to use it in a discussion.
But then again, I'm a fascist and I want to control what everyone is saying. Obviously, my Internet should look like WWII Germany.
