[dude holding a theory book on smug, arguing]
Read theory you losers, you're all WRONG
[dude in an anarchist hoodie, arguing]

[a confused nazi asks]
Why… why are they still arguing?

This is an odd take just considering World War 2 is like the example of unity against a common genocidal threat: the Nazis.
There were no anarchists left in the USSR.
The Soviet Union was established before the Nazis existed. There was no need to ally with anarchists against them when they didn't exist yet and waged war.
A better example would be the Spanish civil war where communists, liberals and anarchists did fight on the same side until infighting broke out due to an ineffective and non-authorative government. Meaning they failed to establish a leading ideology which could have prevented this.
Yeah and that only happened after years of the Nazi party being in power in Germany. And they even got Sudetenland as appeasement by France and Britain without the consent of Czechoslovakia. France and Britain only gave a fuck after Poland was invaded while the rest of Europe tried to stay neutral. And later Italy joined the Nazi. Europe wasn’t very united against the Nazi. Unity of the allies only happened after hundreds of thousands civilians were already executed. Before the invasion of Poland the Nazi executed political opponents and rounded up the Jews in Germany and the world didn’t do shit about it.
Yeah that's why they're stupid. I think it's more of an astroturf op
