Claim: Ayn Rand opposed some ideologies.

Anarchism is a political philosophy that advocates self-governed societies based on voluntary institutions . These are often described as stateless societies , although several authors have defined them more specifically as institutions based on non-hierarchical free associations . Anarchism holds the state to be undesirable , unnecessary , and harmful .   While anti-statism is central , anarchism generally entails opposing authority or hierarchical organisation in the conduct of all human relations , including , but not limited to , the state system . Anarchism is usually considered a radical left-wing ideology , and much of anarchist economics and anarchist legal philosophy reflects anti-authoritarian interpretations of communism , collectivism , syndicalism , mutualism , or participatory economics .   Anarchism does not offer a fixed body of doctrine from a single particular world view , instead fluxing and flowing as a philosophy . Many types and traditions of anarchism exist , not all of which are mutually exclusive . Anarchist schools of thought can differ fundamentally , supporting anything from extreme individualism to complete collectivism . Strains of anarchism have often been divided into the categories of social and individualist anarchism or similar dual classifications .
