Fascism is fascism. It is based on authoritarian models, and very often it is associated with a mix of militarism, racism, nationalism, fanaticism, religious fundamentalism, and of course, it is opposed to any form of socialism. The poor and the weak deserve to be exploited and oppressed, because they are inferior. The true leaders of the society should be, as in Plato's Republic, the philosophers and the warriors. And the fascists always see themselves that way--warrior-philosophers.

Now granted, there are many flavors of fascism, but no two are identical, even if they do share much in common. Hitler, Franco, Mussolini, Salazar are all the classic cases, but there are many others. There are even fascists on the Left; Stalin, Castro, Mao, I could go on.

Some are more toxic than others, but they all share one thing, one philosophy in common. They feel they deserve to rule because they and only they know the truth, any one who disagrees is not just mistaken, he is evil. That's why they all have deadly enemies which they constantly seek out and try to destroy, or at least, banish from the body politic. Sometimes the Other is of a different race, or perhaps has different ideas on how economic affairs should be organized, or comes from a different culture or ethnic tradition, or religion. But its always US vs Them for these people.

And you know, I agree with them on that.
