I understand.
Will this Nazi cr@p never go away?
Godwin's law (also Godwin's rule of Nazi analogies) is an adage in Internet culture that was originated by Mike Godwin in 1990. The law states that:
As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.
There is a tradition in many Usenet newsgroups that once such a comparison is made, the thread is over, and whoever mentioned the Nazis has automatically lost whatever argument was in progress. In addition, whoever points out that Godwin's law applies to the thread is also considered to have "lost" the battle, as it is considered poor form to invoke the law explicitly. Godwin's law thus practically guarantees the existence of an upper bound on thread length in those groups. Many people understand Godwin's law to mean this, although (as is clear from the statement of the law above) this is not the original formulation.
