I think the dynamics never really get away from the fact that, when you have a majority female/minority male group in our society, it is contained within the wider social assumption that male things are default. So dynamics either react to that or acknowledge that, even if individuals try not to.
My classes all through university have mostly been that composition. I have found that generally, there is an assumption that male pronouns will be used, and we will expect to read male-authored texts unless the class is very clearly labeled as a women's studies class. But those classes happen within a subject where the profs are still mostly male, so it's hard to know how to analyze it.
OTOH, my department now has a female majority at graduate, lecturer and prof level and I have found it to be a very supportive environment for women. There is a huge emphasis on collaboration. I have a theory that the patriarchy likes binaries, and that women - who're so often pushed to the outside - are very good at deconstructing or destabilizing binaries and, instead, seeing the grey areas. I suspect it's not coincidental that the department I'm in is interdisciplinary as well as female-dominated.
But, of course, all the nice things I'm saying about it go with the rider that many people there have, and are aware of, the misogyny in other areas, so it's like a safe space, rather than a space that happens to have lots of women.
Interesting topic, thanks.
