Feminist SF

We could try, here, to write an encyclopedia-entry style of definition. It should include several different answers:

- Feminist sf is work that qualifies as feminist by the standards of judgement of various feminisms. (What are those standards?)

- There is a historical feminist sf of works that have been considered by feminists to be central to an ongoing literary conversation

- Feminist sf as a particular feminist literary movement of the 70s and early 80s
