At this point "fascist" is more of an insult than an ideology, very few people who get called "fascist" ever actually live up to any reasonable definition of the word.

> My understanding of fascism is that it is a political system that is founded on a story of lost national glory that can only be restored by a purification of the land by a strong leader

Fascism strikes me as a historical term more than a political one. Its most-commonly agreed upon definition is something like political economic systems that resemble those of Mussolini's Italy and Nazi Germany. (Both governments embraced revanchism. Both were ideologically incoherent.)

That might be the old definition of fascism; but like many words, it has been completely redefined in today's political climate.

The new definition, it seems, is anyone to disagrees with your political viewpoint and makes an effort to push back. Under this definition, it is politically convenient to call your opponent one and be technically right; regardless of where on the political spectrum you find yourself.
