Application of Godwin’s law is just a way to shut down a conversation.
It’s no different from minimalizing what Hitler did. Fact is, what Hitler did was huge, even by historical standards. There have been many, many mass murderers in history, but what the nazis did was beyond them all.
Is that still going to be a subject of conversation 60 years later? I should damn well hope so. Is it still going to be a cultural reference point, a hard rock at which we say “this opitimizes evil; we define evil by this”? Again, I should damn well hope so.
To hell with messr Godwin, and his evil-minimalizing law.
