How is totalitarianism different from other forms of nondemocratic rule?
Individual freedom is restricted. Nondemocratic regimes may be institutionalized and legitimate. Totalitarianism, which should not be confused with authoritarianism, connotes violence and terror, and so people often use the word in a partisan way to label a political system that they particularly dislike.
Why have some scholars suggested that the concept of totalitarianism be abandoned in comparative politics?
Totalitarianism is a form of government in which the ruler is an absolute dictator. Totalitarian regimes have virtually zero pluralism. Example, Nazism, which promoted both biological racism and anti-Semitism under Hitler's goal to achieve an Aryan society, one of blonde-haired and blue-eyed people.
