It's a word that is being used far too often...in far too many places where it is wildly out of context. It is most often used by people who want to browbeat and demonize someone they don't agree with, and place themselves, correspondingly, as being in an unassailable position of supposed moral superiority...akin to the victims of Hitler's Nazi Germany. As such, it's use is getting way out of hand.

As was said above, "Attempting to raise one's profile by invoking the name of Hitler may even work in the short term, but eventually it will be seen for what it is: A dismal attempt at self-promotion. The issue being advocated gets lost in the condemnation that ensues."

That doesn't mean the word "Nazi" should never be used in common dialogue or political dialogue. It should just be used a whole lot less often than it is, that's all, and a whole lot less hyocritically and manipulatively too, since those politicians and spokesmen who have been using it as a label to attack their enemies often seem to me to be quite adept at emulating it in various ways themselves.

In other words, I think the pot has been calling the kettle black in more than a few cases lately.
