This is interesting and I will have to think about a book that I feel is worth wile reading. On the topic of Western Feminism, though, I read an essay by Saba Mahmood about the Women's Egyptian Mosque Movement. Essentially women in this movement all come from fairly secular middle class backgrounds but all choose to embrace a someone fundamentalist form of Islam. While many of their teachings revolve around things that most feminists would abhor (learning "modesty," subservience etc), in fact they are actually very much engaging in a feminist praxis. For example, fundamentalist Islam does not allow women to teach the Quran. Second, the women involved in this movement, in teaching each other, are participating in a form of collective autonomy (something most feminists would support). Nonetheless, they are supporting a patriarchal system even if it is by "choice." The essay really blew my mind actually. It can be little confusing in its use of post-structuralist jargon, but it really made me look at feminism in a different way.
The seclusion of women from men inside an externally patriarchical culture is interesting to examine as a location of women's solidarity and mutual aid. However, from a radical perspective, it is inadequate -- if that radicality is premised on the abolition/negation of various hierarchical institutions. Leila Ahmed's argument that since women created harems that they are therefore locations of women's agency is absurd. The same argument has been made about trade unions. These attempts at counter-power are defensive, perhaps allowing people within them a little extra breathing room in an otherwise thoroughly oppressive situation (patriarchy, capitalism), but they are locations of adaptation, not resistance. If you're only interested in adaptation and finding so-called safe spaces, then fine. But I have always thought of anarchists as people trying to resist and/or destroy oppressive institutions.
btw: the version of this book i have is a totally "outdated" edition of it that's not for sale on amazon (it's a "free copy" made in 1994 for professors, that according to the omniscient authority of the book is NOT intended for student use, that i got at a really really free market.....LOL! You probably won't be able to find it anywhere else....). I checked out amazon for some critique on the book, but all of those editions were made at a minimum of 10 years later....and won't have "free" written all across the inside!
