Anarchism is stuck in a mid 20th century political paradigm. For many anarchists, Nazism remain the largest global political threat, and the baseline comparison for every authoritarian ideology is fascism. This explains why some of the most visible anarchist mobilisations in recent years were farcical "anti-fascist" street fights in places like Portland and Berkeley. It also explain why anarchists prioritise anti-semitism over things like anti-Palestinian racism, although they nominally oppose both. Jews are still seen as a marginalised group, even though they do not face discrimination on account of their ethno-religious identity in the West.
There's a noticeable absence of specifically anarchist mobilisation when it comes to Zionism and the American-Israeli war on Iran. Strangely, most of the war related discourse in anarchist circles targets Iran supporting tankies, who are politically irrelevant, instead of the US.
Today the state power in the West is wielded by conservatives, liberals and Zionists, all of whom are capitalist. "Nazi" is at best an inaccurate slur directed towards these groups. In the 21st century, Nazis are powerless and politically irrelevant, just like tankies.
Outside the West, there's more political diversity, including liberal democracies that veer between conservatism and liberalism, monarchies, dictatorships, one party technocracies and theocracies. However, there isn't anything closely resembling Nazi Germany. If anything, the closest examples are the Scandinavian states, because social democracy is the political economy of fascism.
There are, however, small and isolated Nazi movements in many countries, which anarchists choose to spend a disproportionate amount of time focusing on. One potential reason for this is the political irrelevancy of anarchism. The only way anarchists can exercise their own views is through inane street brawls. The squats of Exarchia have been cleared out, Freetown Christiania is a state sanctioned tourist attraction, and third world anarchist movements are run from US based anonymous Twitter accounts.
Anarchist thought, aside from left-wing market anarchism, is also stuck in the 20th century. In terms of political and economic theory, anarchism has stagnated, and the old guard is very much hostile to new ideas. To this day, market anarchists are seen as capitalists.
It really feels like anarchism is stuck in an epiphenomenal loop, where the struggles of the 20th century are played out over and over again. The same factions, the same fracturing of left-unity, and the same betrayals. It's all very boring and uninspiring.
