As I recall mentioning the tendency for people to bring up the Nazis on IRC and Usenet in the late '80s—well before Godwin wrote about it—I suggest we call it
Bennett's Law.
However, my point still stands.
Look how Rudd has now
persuaded herself that no-deal is now
manageable rather than, as she had previously remarked, would
“do generational damage to our economy and security”.
All you need to do is move your moral goalposts (in this case after cushy job offer) and anything becomes potentially achievable (even desirable)—including the apocalypse.
