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

- If we look at what has been considered SF and what has not in the 19th century, the genre could stand some redefining. Gothic romance and the supernatural should at least be included in definitions of "speculative fiction".
