Godwin's law was just a humorous observation that the longer online discussions go on, the more likely someone is to bring in a Nazi analogy. The funny part about this, besides it being true, is that everyone in such discussions has had experience with Nazi's being used in a lazy or hyperbolic way to attack something far less serious.
Godwin said himself that doesn't mean there aren't circumstances where ideas truly are Nazi-like or would defend what the Nazi's did and it is worth pointing this out.
People would refer to Godwin's law in the context of saying that if you were the one who brought up Nazis, there's a good chance you are losing the argument and are relying on exaggeration where sound explanation has failed you.
MADB, via Juliann, had a bizarre interpretation that "Godwin's law" meant that if you compare anything, literally anything, to the Nazis then you've lost the argument and this justifies censoring you. She misunderstood what the word "law" meant in that phrase and thought it was a rule about appropriate communication. MADB would invoke it in circumstances where bringing up Nazis was an obvious and appropriate response. But that's unique to this quirky corner in the niche world of online LDS apologia.
For what it is worth, Mike Godwin himself has gone on record imploring people to compare contemporary people in American politics - see if you can guess which ones - to Nazis:
