Fascism was a counter-revolution against a revolution that never took place.

Fascism is a false revolution. It cultivates the appearance of popular politics and a revolutionary aura without offering a genuine revolutionary class content. It propagates a "New Order" while serving the same old moneyed interests. Its leaders are not guilty of confusion, but of deception. That they work hard to mislead the public does not mean they themselves are misled.

Fascism is anti-Marxism which seeks to destroy the enemy by the evolvement of a radically opposed and yet related ideology and by the use of almost identical and yet typically modified methods, always, however within the unyielding framework of national self-assertion and autonomy. This definition implies that without Marxism there is no fascism, that fascism is at the same time closer to and further from communism than is liberal anti-communism, that it necessarily shows at least an inclination toward a radical ideology, that fascism should never be said to exist in the absence of at least the rudiments of an organization and propaganda comparable to those of Marxism.

[Fascism] was an explosion against intolerable conditions, against remediable wrongs which the old world failed to remedy. It was a movement to secure national renaissance by people who felt themselves threatened with decline into decadence and death and were determined to live, and live greatly.

Fascism is a deformity of capitalism. It heightens the imperialist tendency towards domination which is inherent in capitalism, and it safeguards the principle of private property. At the same time, fascism immeasurably strengthens the institutional racism already bred by capitalism, whether it be against Jews (as in Hitler’s case) or against African peoples (as in the ideology of Portugal’s Salazar and the leaders of South Africa). Fascism reverses the political gains of the bourgeois democratic system such as free elections, , parliaments; and it also extolls authoritarianism and the reactionary union of the church with the state. In Portugal and Spain, it was the Catholic church—in South Africa, it was the Dutch Reformed church.

Fascism must be seen as an episodically logical stage in the socio-economic development of capitalism in a state of crisis. It is the result of a revolutionary thrust that was weak and miscarried — a consciousness that was compromised.

As the 1983 American Heritage Dictionary noted, fascism is: “A system of government that exercises a dictatorship of the extreme right, typically through the merging of state and business leadership, together with belligerent nationalism.”...Mussolini was quite straightforward about all this. In a 1923 pamphlet titled “The Doctrine of Fascism” he wrote, “If classical liberalism spells individualism, Fascism spells government.” But not a government of, by, and for We The People—instead, it would be a government of, by, and for the most powerful corporate interests in the nation.

Fascism is used by the bourgeoisie when the latter consider itself no longer able to fight off the peril of a socialist revolution. Fascism is, therefore, organic to the logics of capitalism and represents a more authoritarian handling that bosses temporary use, when necessary, in order to maintain their rule.

Fascism may be defined as a form of political behavior marked by obsessive preoccupation with community decline, humiliation, or victim-hood and by compensatory cults of unity, energy, and purity, in which a mass-based party of committed nationalist militants, working in uneasy but effective collaboration with traditional elites, abandons democratic liberties and pursues with redemptive violence and without ethical or legal restraints goals of internal cleansing and external expansion.

Fascism is perhaps best defined as a pathological conservatism: the elements of conservatism warped and twisted into a parody of themselves, by concentration on certain selected symbols (particularly the nation), which are mystified and deified.

Fascism is a religion of the state. It assumes the organic unity of the body politic and longs for a national leader attuned to the will of the people. It is totalitarian in that it views everything as political and holds that any action by the state is justified to achieve the common goal. It takes responsibility for all aspects of life, including our health and well-being, and seeks to impose uniformity of thought and action, whether by force or through regulation and social pressure. Everything, including economy and religion, must be aligned with its objectives. Any rival identity is part of the "problem" and therefore defined as the enemy. I will argue that contemporary American liberalism embodies all of these aspects of fascism... You can see why the Marxist left would resist the idea that Hitler was a revolutionary. Because if he was, then either Hitler was a force for good, or revolutions can be bad.

Fascism is a caricature of Jacobinism.

Fascism is capitalism in decay.

Fascism is the bourgeoisie’s fighting organisation that relies on the active support of Social-Democracy. Social-Democracy is objectively the moderate wing of fascism.
