No, what you should takeaway is that misoverusing the term Nazi as an insult
patently no longer works precisely because noone cares about being called a Nazi anymore due to its misoveruse.
In a different timeline, Trump being called a Nazi or any of the vicinity terms should have been an immediate termination of his campaign chances.
What actually happened is Trump ignored it (as he should) and the American people shrugged "OK" and went to vote for him with complete disregard.
Then Musk got called a Nazi at the inauguration, and the American people shrugged "OK" and went back to facepalming at just how much sheer waste the government has with complete disregard.
The moral you should take away is you should not invoke Godwin's Law. It's probably too late for "Nazi", "racism", "sexism", and a host of other insults the Left have thrown around to see what sticks (none have), but that doesn't mean future originally-valuable-terminology have to face the same fate.
Another moral is that insulting Americans probably doesn't actually work in general. "Deplorables", "Garbage", and others were turned around into rallying cries during the 2016 and 2024 campaigns, not unlike the original meaning behind the term "Yankee" which was originally an insult not unlike "Kraut" or "Jap" but is now one of the fondest nicknames of Americans.
