The silence of the Left, or the exclusive focus of the Left, on America's alleged crimes over the past half-century, the disdainful sneering at America's deplorable 'Cold War mentality' - none of this has to be reassessed in light of the evidence of genocides that surpassed Hitler's, all in the name of a Marxist ideology. An ideology that doesn't need to be reassessed. As if it was maybe just an accident that Marxist-Leninist regimes turned totalitarian and genocidal. No connection there.
