as left-libertarians and see themselves as being part of a broad libertarian left. While the term libertarian has been largely synonymous with anarchism as part of the left, continuing today as part of the libertarian left in opposition to the moderate left such as social democracy or authoritarian and statist socialism, its meaning has more recently diluted with wider adoption from ideologically disparate groups, including the right. As a term, libertarian can include both the New Left Marxists (who do not associate with a vanguard party) and extreme liberals (primarily concerned with civil liberties) or civil libertarians. Additionally, some libertarians use the term libertarian socialist to avoid anarchism's negative connotations and emphasize its connections with socialism.Guérin, Daniel (1970). Anarchism: From Theory to Practice. New York City: Monthly Review Press. p. 12. "[A]narchism is really a synonym for socialism. The anarchist is primarily a socialist whose aim is to abolish the exploitation of man by man. Anarchism is only one of the streams of socialist thought, that stream whose main components are concern for liberty and haste to abolish the State." . The revival of free-market ideologies during the mid- to late 20th century came with disagreement over what to call the movement. While many of its adherents prefer the term libertarian, many conservative libertarians reject the term's association with the 1960s New Left and its connotations of libertine hedonism. The movement is divided over the use of conservatism as an alternative. Those who seek both economic and social liberty would be known as liberals, but that term developed associations opposite of the limited government, low-taxation, minimal state advocated by the movement. Name variants of the free-market revival movement include classical liberalism, economic liberalism, free-market liberalism and neoliberalism. As a term, libertarian or economic libertarian has the most colloquial acceptance to describe a member of the movement, with the latter term being based on both the ideology's primacy of economics and its distinction from libertarians of the New Left. While both historical libertarianism and contemporary economic libertarianism share general antipathy towards power by government authority, the latter exempts power wielded through free-market capitalism. Historically, libertarians including Herbert Spencer and Max Stirner supported the protection of an individual's freedom from powers of government and private ownership. In contrast, while condemning governmental encroachment on personal liberties, modern American libertarians support freedoms on the basis of their agreement with private property rights.
