Found an article on promoting Feminism in the Sci-Fi/Fantasy genres. It quotes a speech of Nancy Moore’s that lists the kind of stories and books she’d define loosely as feminist:
1. SF and fantasy adventure stories in which women are the lead characters having the adventures.
2. Complex works that tell the stories of women acting in the world in a much broader scope than the roles allowed them in the past.
3. Works by and about men that address issues of gender–such as that by recent Tiptree winners. John Kessel’s “Stories for Men” is one example.
4. Sophisticated science fiction that takes on the possibilities opening up from biology–and artificial intelligence as well–and makes us re-think everything we’ve ever thought we understood about gender.
Number 2 would almost certainly apply, at least in the 60s, given that at its Silver Age concept it doesn’t single out either gender, and after Katma Tui we learn that female Lanterns accepted and normal. Not to mention Carol, not only being able to pilot an aircraft (this is what she was doing when she got drafted as Star Sapphire) but running the company and being her boyfriend’s boss. Nowadays, though, it could be argued that female roles shifted and the traditional role of women in comics opened up to not only allow a wider range of occupations for female characters, but also allow heroic women as love interests. Then, as the female supporting cast in Green Lantern shrunk to only those who were love interests (Jade) it left the feminist category.
Which is pretty tragic when you think on it.
