Left as an Exercise

Definition 1: Godwin’s Law
As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.

Definition 2: Unnamed (longstanding tradition re: Godwin’s Law)
After a Nazi or Hitler comparison is made, the thread is over. He who has made such a comparison has just lost.

Definition 3: Quirke’s Exception
Any intentional triggering of Godwin’s Law in order to invoke its thread-ending effects will be unsuccessful. (That is, the exception to Godwin’s Law is intentionally invoking Godwin’s Law.)

Definition 4: Monckton’s Exception
Comparisons of nonviolent activists to the Hitler Youth are kosher, even face-to-face, and especially if the person you’re speaking to is Jewish. (See also: Monckton’s Justification and Monckton’s Solution).

If you’re unfamiliar with this exception’s namesake, pick a random article or two and see for yourself. If he didn’t exist, comedians would have to invent him - but the comedians would have the good taste to keep him locked away and medicated rather than letting him try to influence global policy with his conspiracy theories.
