I'm sorry but what? This is really weird logic as language and words aren't required to follow some linear path of severity. People call the GOP, Trump and the like Nazis because... they fit the definition of Nazis, actual card carrying Nazis support them by a significant majority. (Yeah yeah I know there is the odd one here or there that doesn't)

If it walks like a Nazi, talks like a Nazi and engages in Nazi tactics, behaviors etc. Then it can be called a Nazi. You don't reserve your language so that you have some end point to progress to.

It's also very weird to use the boy who cried wolf when the whole point of that story is that you don't call something that which it isn't for fear that when the real thing comes along no one will believe you as that would imply that they are in fact not Nazis. Which would only be true in the most technical of sense (As in they are not of the Nazi party of Germany) but by most dictionary definition the word fits.

Lastly, what the hell are you even talking about "edgy"? Do you think people are calling them Nazis to be edgy? Because that's ridiculous and quite frankly your entire comment screams of someone trying to defend them through deflection.
