North Korea is it's own, special form of evil which has developed nukes at the expense of nearly their entire GDP, most work is compelled, executed a general by antiaircraft gun, keeps people from escaping, still technically at war (ceasation of hositilities but still points AKs across the border) with the South and starves millions to death. Perhaps the mentioning of Godwin's law is itself groupthink dismissing legitimate "evil" suspects like Drumpf, Assad, Putin, Daesh, etc., that need more nuanced discussion, not shutting down. Shutting down is for tinfoil hat "micro-aggressions" and bikeshedding femto-issues, not ruthless regimes which genocidally-eradicate their own populace to ensure their own survival.
Godwin's law has come full circle to the point where it's invoked even where the comparisons make sense. The Nazi party of WWII and the atrocities committed by them are not entirely incomparable, even if they are often used hyperbolically. Reserving a special place for those actions and refusing comparison invites us to ignore when the comparisons are apt, and to see the connections where they are relevant.
In some respects, North Korea is far worse than Nazism ever was (such as in its fanatacism), but in others it's nowhere near (such as the Holocaust, unless the situation there is far, far worse than anyone knows).
WW2 was a significant event in world history, it has relevance in many areas. It's also a great example of unique issues. It undoubtedly has relevance to many, varied subjects. as such, Godwins law is unproductive memetic junk.
