Ever call somebody a fascist, but never knew what it meant? I sure have, and I've seen other people do the same.

In the interests of truthful name-calling, here's a primer from The Holocaust Memorial Museum. An in-depth primer from their study guide here.

Absolutism or Relativism?
"There is no such thing as truth either in the moral or in the scientific sense. The needs of the State are the sole determining factor. What may be necessary today need not be so tomorrow. This is not a question of theoretical suppositions, but of practical decision dictated by existing circumstances. Therefore, I may -- nay -- must --change or repudiate under changed conditions tomorrow what I consider correct today"
— Adolph Hitler – Rauschning, The Voice of Destruction, pp. 223
"Everything I have said and done in htese last years is relativism by intuition... If relativism signifies contempt for fixed categories and men who claim to be the bearers of an objective, immortal truth... then there is nothing more relativistic than fascistic attitudes and activity... From the fact that all ideologies are of equal value, that all ideologies are mere fictions, the modern relativist infers that everybody has the right to create for himself his own ideology and to attempt to enforce it with all the energy of which he is capable."
-Mussolini, Diuturna, p. 374-77
"Members and front organizations must continually embarrass, discredit, and degrade our critics. When obstructionists become too irritating, label them as fascist or Nazi or anti-Semitic. Constantly associate those who oppose us with those names that already have a bad smell. The association will, after enough repetition, become 'fact' in the public mind."

Am I a Fascist?

Self-criticism is always a good thing. Its best to call yourself what you think you are not, just to see if you might happen to be the very thing you condemn.

From the aforementioned Holocaust museum primer:

Fascism and Nazism as ideologies involve, to varying degrees, some of the following hallmarks:
(my comments in italics)

1. Nationalism and super-patriotism with a sense of historic mission.
Nope. Not me. I don't have anything against the typical American patriotism, though, which only involves the minor use of recreational explosives on July 4th.

2. Aggressive militarism even to the extent of glorifying war as good for the national or individual spirit.
Nope again... War is hell, though sometimes one has to march through it..

3. Use of violence or threats of violence to impose views on others (fascism and Nazism both employed street violence and state violence at different moments in their development).
Nope. Violence stinks just about all of the time.

4. Authoritarian reliance on a leader or elite not constitutionally responsible to an electorate.
Not me.

5. Cult of personality around a charismatic leader.
Not me again.

6. Reaction against the values of Modernism, usually with emotional attacks against both liberalism and communism.
Aha, almost, but not quite. I'm not so much anti-Enlightenment/Modernism as pre-Enlightenment/Modernity. Yeah, I don't like communism, or what passes for liberalism nowadays, and I sometimes emotionally attack it. So I guess I may call this a half-accurate description of me. 0.5/11 fascist so far...

7. Exhortations for the homogeneous masses of common folk (Volkish in German, Populist in the U.S.) to join voluntarily in a heroic mission_often metaphysical and romanticized in character.
My Old response: "Who said the common folk were homogeneous? Yeah, I'm a Romantic populist, so I guess I this one gets all the way checked off. 1.5/11 Fascist so far..."
Recently, however, I learned that homogeniety was, in fact, stressed by the fascisti. I had thought somebody was just being elitist. I'm only giving myself 1/2 a point now. Score: 1/11

8. Dehumanization and scapegoating of the enemy_seeing the enemy as an inferior or subhuman force, perhaps involved in a conspiracy that justifies eradicating them.
Nope. Everybody's human, even when they don't act like it... On Honor in ideologic quarrels.

9. The self image of being a superior form of social organization beyond socialism, capitalism and democracy.
Well, I'm kind of a Distributist right now, but one could make the argument that it is merely a slightly tweaked form of Capitalism, and a thoroughly democratic one at that.

10. Elements of national socialist ideological roots, for example, ostensible support for the industrial working class or farmers; but ultimately, the forging of an alliance with an elite sector of society.
As far as I know, my support is genuine.

11. Abandonment of any consistent ideology in a drive for state power.
Nope. My Total score: 1/11 Fascist. Not bad, I think.

Fascism - A philosophy or system of government that advocates or exercises a dictatorship of the extreme right, typically through the merging of state and business leadership, together with an ideology of belligerent nationalism.
