Do you really mean MN, or do you just mean the specifically feminist sections of MN?
MN is a site about women by women for women. That is what makes it so great. On almost any other forum, things that impact only or mostly women are ignorede or shunted into a Feminism thread, or even worse, a Women's Chat thread.
But on MN, where women's concerns are front and centre, the topics you are flagging aren't specifically in Feminism because they are all over the site, turning up in education threads, in relationship threads, in AIBU threads, in property threads, in legal threads.
This is, if you like, small-f feminism. It's women supporting women by dealing practically with the specific instances of shit that impact women's life. When shit is hitting the fan the underlying Why this happens (women's lesser voices and lesser political, economic and cultural power, the asymetric impact of parenthood etc) is less important than the What needs to be done right now.
And of course the women who comment under one name in FWR may well have another name they use in the rest of the site, because too many nasty men consider it a sport to identity women with whom they disagree online IRL and harass them.
And then there is big-F Feminism, the social and political analysis and activism that links all that small-f shit together and aims to tackle the source it springs from. On MN, the Feminist boards tend to be more big-F feminism not because that's all MN feminists care about but because unlike male-dominated sites, on MN the small-f feminism happens under the specific topic for each problem. And right now, redefining womanhood itself, unwriting the impact of biology and patriachy and replacing it with the idea of "womanny minds" is a pretty huge social change that big F feminism needs to understand and (IMO) challenge. Even if your view is it is a good thing, there's still a load of big-F questions raised that GAFs (gender accepting feminists) need to grapple with to work out how feminism and women's supports can best accomodate male women without disadvantaging the female ones.
