[note: the above is not an exclusive list and obviously there are differences between the groups and positions mentioned above, its to give the range of perspectives that this group would cater to and to mention ideological positions and groups that are historically or politically related to the new left as distinct from old left or post-modernist 'post-left'.]
Who this is not for:
-Sectarian/anti-Cuban Anti-Revisionists, people who advance the theory of 'social imperialism' to the point of openly supporting imperialist (i.e. NATO) reaction against contemporary and former socialist (or revisionist) states
-Active endorsers of Eurocommunism, "Democratic Socialism", and other forms of social-democratic reformism under the banner of communism
-Orthodox Trotskyists, Cliffites, anyone who calls for the overthrow of existing workers states rather than their defense or anyone who takes a third camp line in geopolitical issues.
-People who advance the theory of 'state capitalism' rather then degenerated/bureaucratic/revisionist socialism (Left-Communists, Cliffites, third camp Trotskyists and Ultra-left Maoists)
-People who obsessively support any dead creepy small state communist leader (such as Hoxha, Ceausescu, Pol Pot, "Jim Jones" etc) or who take a "stalinogothic lifestylist" rather than a contemporary Marxist-Leninist position.
-Militant defense of socialist states, ('tankie'/cold-war geopolitics). This also means contemporary socialist societies (although debatable in which degree) like Cuba, Nepal, Vietnam, Laos, and the DPRK
-Libertarian social theory, with radical approaches to all social issues, including socialist feminism, gay liberation, youth liberation, and oppressed internal semi-colonies etc./rejection of paternalism in all of its forms including anti-drug, anti-sex, and anti-rock and roll (kidding) positions.
-Acceptance of Lenin's theory of Imperialism, including labour aristocracy and imperialist super-profits while recognizing that hyper-exploited people exist in the first world.
Possible theoretical issues:
How much of Maoism is correct; Bolivarianism, mechanisms for co-opted labour and to what extent labour in imperialist centres is co-opted; national chauvinism in the first world left and in westernized third world parties, whether it exists or not, and if so its causes; the status of Venezuela and Nepal; the movement in India; existentialist social theory and philosophy; what can communists do of use in the first world; the relationship between patriarchy and capitalism; social libertarianism vs communitarian/paternalist leftwing views of social issues; etc...
I would also suggest that the above would be the guidelines in terms of the ethos and 'official' politics but that with the consensus the people who accept them people who fit with the attitude and general perspective but differ on particular points could be admitted.
