One of the most frustrating aspects of this sub when it comes to the gatekeeping, is that a lot of right-libertarians haven’t even read the first 1 or 2 PARAGRAPHS on the Wikipedia page for “Libertarianism,” let alone any primary sources.
Here they are for your wonderful convenience, btw:
Libertarianism (from French: libertaire, “libertarian”; from Latin: libertas, “freedom”) is a political philosophy and movement that upholds liberty as a core principle. Libertarians seek to maximize autonomy and political freedom, emphasizing free association, freedom of choice, individualism and voluntary association. Libertarians share a skepticism of authority and state power, but some of them diverge on the scope of their opposition to existing economic and political systems. Various schools of libertarian thought offer a range of views regarding the legitimate functions of state and private power, often calling for the restriction or dissolution of coercive social institutions. Different categorizations have been used to distinguish various forms of libertarianism. Scholars distinguish libertarian views on the nature of property and capital, usually along left–right or socialist–capitalist lines.
Libertarianism originated as a form of left-wing politics such as anti-authoritarian and anti-state socialists like anarchists, especially social anarchists, but more generally libertarian communists/Marxists and libertarian socialists. These libertarians seek to abolish capitalism and private ownership of the means of production, or else to restrict their purview or effects to usufruct property norms, in favor of common or cooperative ownership and management, viewing private property as a barrier to freedom and liberty.
