I would argue with the implication that the degree to which a story is political is gauged by how violent (in the broad sense) the political actions are. Something can be extremely pacifistic or extremely democratic for example. In star trek you have a tremendous numer of stories where non-violent political actions like diplomacy, legislation, or legal argument are the main focus of the story and hugely consequential, for an entire people, an entire species, or the entire galaxy.
