The main tenets of libertarianism emphasize individual freedom, limited government, and free-market principles. Libertarians advocate for minimal state intervention in personal lives and economic activities, believing that individuals should have the right to make their own choices as long as they do not infringe on the rights of others. They promote civil liberties and privacy, along with a non-interventionist foreign policy. Libertarians often oppose government regulations and welfare programs, arguing that a free market leads to optimal resource allocation and enhances overall societal well-being.
