You especially won’t hear about it from anarchists. They just go on and on about how M-Ls betrayed them and conveniently leave out that those anarchists literally allied with invading imperialists.

Also, terror has sadly been unavoidable as an instrument of war. That’s always been true for any conflict. Liberals exceptionalizing the red terror also conveniently never mention the atrocities and errors committed by all sides from their own revolutions and civil wars.
