Godwin's law, which usually indicates a weak argument and a lazy mind.

Godwin's law (also known as Godwin's Rule of Nazi Analogies or Godwin's Law of Nazi Analogies)[1][2] is a humorous observation made by Mike Godwin in 1989 which has become an Internet adage. It states: "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1."[3][2] In other words, Godwin put forth the sarcastic observation that, given enough time, all discussions—regardless of topic or scope—inevitably end up being about Hitler and the Nazis.
