And why are anarchists pretending to know shit about fascism? Anarchism does not have such a coherent theory that it may criticise or understand the world, it does not have a unified concept of history or historical causality. Neither does it have political structures that can legitimise certain theoretical conclusions over others or even establish schools of thought. It is just a grab bag of banal critiques of feelings of alienation endemic to modern society and mostly operates at the level of feelings.
But let us flip anarchism on its head! There is a reason anarchism persists among the petty-bourgeois while Marxism (especially his critique of Kropotkin) is unbearable. For anarchism, there is direct continuity between slavery/serfdom and capitalism, with merely a chance in oppressors "stealing" our labor. Capitalists interfere with the direct relationship between nature and humanity, and eliminating them will restore the non-alienated labor of individual skill and "affective labor." In concrete terms, individual producers in voluntary organizations can link together without the parasitism of capitalists. This is a quite common fantasy even among the frauds who nefariously claim that the "end state" of Marxism and anarchism are the same, that there are merely tactical or strategic differences getting there. The petty-bourgeois, utopian nature of this should be obvious, as non-alienated labor/individual free subjectivity is already pregiven but has been robbed by the Other and must be restored so that individuality can again flourish.
The important thing is that the Function of the Jew is absolutely essential in an anarchist worldview because some third force must exist which turns human relations into exploiter/exploited outside of the laws of motion of that relation. Whether it is the fantasy of small, decentralized communes cooperating, the market opposed to "capitalism," the state as external and autonomous, or even the concept of hierarchy itself, the core of Marxist anti-humanism - that relations produce their own subjects and therefore all of the tools of the proletariat (the vanguard party, the planned economy, the dictatorship of the proletariat) are not external to class consciousness but are produced by and produce it, is impossible! Utopian socialism must have an explanation for the fall from utopia and a belief in the innate qualities of nature and humanity which have been robbed by the Other.
Of course nature does not exist, it is produced by social relations and changes with social relations. It shouldn't surprise anyone then that communists (or "tankies" in the crude version) serve as the Jews that cause the social antagonism and corrupt nature to Westerners raised on anti-communism and with a material interest in it.
For Marxists, anarchism (a form of liberalism) and fascism are one and the same though at different dialectical moments in the movement of capital.
And the Marxist conception of fascism? No worries, I won't leave you hanging.
Fascism is a general reactionary illiberalism coming out of the dispossessed petty bourgeoisie. But while this definition is precise, ultimately the line between petty bourgeois and bourgeois reaction is often quite blurry, the content is essentially the same for colonised people. Take Japan for example. When did Japan become fascist? Was it 1868, when the emperor, the bourgeoisie, and the former landowners collaborated to violently develop the nation along state-capitalist lines? Was it 1905, when Korea was truly opened up for Japanese imperialist exploitation and Japan implemented a police state? Was it 1936, when the February 26th incident ended any pretense of liberalism? Was it 1944, when the desperate conditions of the war turned the Japanese homeland into a total police state with forced labor and suicidal economic policy?
It was all of these, and fascism is an integral part of the normal functioning of capitalism. Subhas Chandra Bose was right and the only difference between the democracy of Britain and the fascism of Germany was that Germany was stupid enough to impose terror on its own population instead of exporting it to India.
