Countermeme designed against offensive meme.

This is a one example of Memetic Engineering.  Once you can find a Meme and name it, label it and let other see they are using it, it often looses it's power.

Once you can name learn to spot and describe a Meme, you can start to control it.

Find a new rhetorical hammer

In 1990, Godwin got fed up with Nazi comparisons on bulletin boards, Usenet newsgroups, and the WELL discussion site. So prevalent had these comparisons become that Godwin began to wonder “how debates had ever occurred without having that handy rhetorical hammer.”

He believed that most of these comparisons simply trivialized the Holocaust and the true horror of the Nazi regime and so consciously decided to build a “countermeme designed to make discussion participants see how they were (and are) acting as vectors to a particularly silly and offensive meme.”

The result was Godwin's Law in its original form:

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