Social democracy is officially a reformist democratic socialist political ideology. Social democracy supports legal entitlements in social rights for citizens. These are made up of universal access to public services such as: education, health care, workers' compensation, and other services such as child care and care for the elderly. Social democracy is connected with the trade union labour movement and supports collective bargaining rights for workers. Contemporary social democracy advocates freedom from discrimination based on differences of: ability/disability, age, class, ethnicity, gender, language, race, religion, and sexual orientation. Most social democratic parties are affiliated with the Socialist International.

Social democracy in its current form was originally developed by revisionist Marxist Eduard Bernstein who criticized orthodox Marxism's emphasis on revolution and class conflict, claiming that socialism could be achieved through evolutionary means through representative democracy and through cooperation between people regardless of class. Bernstein claimed that a mixed economy of public, cooperative and private enterprise would be necessary for a long period of time before private enterprises would evolve of their own accord into cooperative enterprise. Bernstein supported state ownership only for certain parts of the economy that could be best managed by the state, he rejected a mass scale of state ownership as being too burdensome to be manageable.

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.

Tony Robert Judt, FBA (2 January 1948 – 6 August 2010) (pronounced Jutt) was a British historian, essayist, and university professor who specialized in European history. Judt moved to New York and served as the Erich Maria Remarque Professor in European Studies at New York University, and Director of NYU's Erich Maria Remarque Institute. He was a frequent contributor to the New York Review of Books. In 1996 Judt was elected a Fellow of the American Academy of Arts and Sciences and in 2007 a corresponding Fellow of the British Academy.

A Marxist Zionist as a young man, Judt dropped his faith in Zionism after youthful experience in Israel in the 1960s and came to see a Jewish state as an anachronism; he moved away from Marxism in the 1970s and 1980s. In later life, he described himself as "a universalist social democrat". Judt's works include the highly acclaimed Postwar, a history of Europe after the Second World War. He was also well known for his views on Israel, which generated significant debate after he advocated a one-state solution to the Israeli–Palestinian conflict.

Takis Fotopoulos (Τάκης Φωτόπουλος) (born October 14, 1940) is a political philosopher and economist who founded the inclusive democracy movement. He is noted for his synthesis of classical democracy with libertarian socialism and the radical currents in the new social movements. He was an academic, and has written many books and over 900 articles, several of which have been translated into various languages. He is the editor of The International Journal of Inclusive Democracy (which succeeded Democracy & Nature) and author of Towards An Inclusive Democracy in which the foundations of the inclusive democracy project were set. Fotopoulos is Greek and lives in London.

Fotopoulos was born in the Greek island of Chios and his family moved to Athens soon afterwards. After earning degrees in Economics and Political Science and in Law from the University of Athens, he moved to London in 1966 for postgraduate study at the London School of Economics on a Varvaressos scholarship from Athens University. He was a student syndicalist and activist in Athens and then a political activist in London, taking an active part in the 1968 student movement in London, as well as in organisations of the revolutionary Greek Left during the struggle against the military junta in Greece (1967–74). During this period, he was a member of the Revolutionary Socialist Groups in London, which published the newspaper Μαμή ("Midwife", from the Marxian dictum, "violence is the midwife of revolution"), for which he wrote several articles.
