Godwin's law : Godwin's law (or Godwin's Rule of Nazi Analogies) is an Internet adage asserting that "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1"— that is, if an online discussion (regardless of topic or scope) goes on long enough, sooner or later someone will compare someone or something to Hitler or Nazism.
"Before you rant, please read tips for the angry new user." [1]
