The fallacy of attributing all
responsibility for a complex phenomenon to a single cause, agent, or system—most famously, the claim that "this is solely and exclusively the fault of communism." The fallacy ignores that complex historical events have multiple causes, that
responsibility is often distributed, that systems interact, that context matters. It's the logic of "communism killed millions" used to end discussion, as if that single factor explained everything—ignoring colonialism, capitalism, imperialism, war, famine, and the myriad other forces that shaped the same events. The Fallacy of Sole and Exclusive Blame is beloved of ideologues who want simple stories, who need clear villains, who can't tolerate complexity. It reduces history to morality play, causation to blame,
understanding to accusation.
Example: "He blamed communism for every death, every famine, every failure—as if
capitalism, colonialism, and
imperialism had killed no one. The Fallacy of Sole and Exclusive Blame had simplified history to a single villain, a single story, a single cause. Complexity was sacrificed for certainty;
understanding was sacrificed for blame."
