The protagonists are essentially altruists whose ideals are sometimes only imperfectly applied to the dilemmas presented in the series. The conflicts and political dimensions of Star Trek form allegories for contemporary cultural realities; Star Trek: The Original Series addressed issues of the 1960s,[2] just as later spin-offs have reflected issues of their respective eras. Issues depicted in the various series include war and peace, authoritarianism, imperialism, class warfare, economics, racism, human rights, sexism and feminism, and the role of technology.[3]
