Godwin’s Law states that as an on-line discussion grows longer, the probability of Hitler or the Nazis being mentioned approaches 100%.
Actually, the law is valid whether the discussion is on-line or anywhere else.
However, in discussions involving Christians, the phenomenon can be broadened and intensified.
In any discussion between Christians, the probably that either Hitler & the Nazis will be mentioned, or Hellfire & Damnation threatened, very soon approaches 100%.
Usually, both, sometimes in the same breath.
