The USSR was not communism. Even if you protest and hold ground that it was communist, it does not represent communism and was objectively separate from anarchism. You argument is akin to saying that the USA is democracy.

Republican-style whataboutism. Nice. I never defended the USSR and this still doesn't change U.S. history.

They’re not wrong in this specific case though.

Why choose other imperialist powers as though this is a representative sample? Unless you're arguing that every country is equally bad--thereby excusing the US from its war crimes--its unclear what these examples are meant to prove.

What anarchists talk about cleansing? Are you referring to the dictatorship of the proletariat in Leninism?

You can't just make things up about an ideology and then argue like the thing you made up is true and well known. That makes you exactly like the meme you're making fun of.

Using violent tactics is not synonymous with war mongering. Maybe a definition helps to differentiate the difference "A warmonger is someone strongly pro-war. Warmongers favor war above all other options."

where does anyone say “our imperialism is the good kind?”

The military industrial complex is pretty well known at this point. I suspect they agree with the message, but don't like that it's coming from someone further left than Democrats.

You could maybe argue that when Biden was in office. Right now it is as much proxy war as Germany and USSR invading Poland in 1939.
