What is "multi-tendency"

Multi-tendency collectivist political organisations, especially left-wing groups, accommodate members who are affiliated to or identify with different political ideologies, agendas, interests or perspectives. The word has been used to describe groupings of social democrats, socialists, human rights advocates, feminists, African-American activists and anarchists who work together in support of a common cause. Multi-tendency pluralistic groups are distinguished from those groups that strictly adhere to a party line or a stringent credo.
