Liberals, as the political scientist Drew Westen has explained, often refrain from the narrative of shared identity, perhaps owing to awareness that great crimes are often committed in its name. Hitler redefined the German Volk as the collective victim of an internal enemy that was tainting its blood – a type of narrative that, whether framed in terms of race, religion, or class, underlies genocide wherever it occurs.
自由派，如政治学家德鲁·威斯腾（Drew Westen）所解释的，常常不提共同身份叙事，也许这是因为他们认识到大罪恶常常也是打着这一旗号犯下的。希特勒将德语词汇Volk（人民）重新定义为污染民族血液的内部敌人的集体受害者——这就是一种类型的叙事，它可以通过种族、宗教或阶级的幌子构建，成为大屠杀的基础。
