Hi Vezzie,
Yes, it could well be that I was mischaracterising rad fem: I'll go and have a look at stewie's link. I read rad fem described in the terms I used earlier in the thread, in an encyclopedia of ethics, but that is just one person's take on it. And additionally I could well have imposed my own preoccupations on the way I read that text.
The perception of the systematic nature of women's maltreatment and disadvantage that you speak of as a defining part of the radical outlook, I've always thought of as being characteristic of feminism itself rather than of any subfeminism?
Difference feminism (I think sometimes called gynocentric feminism) seems perched on the edge of being accidentally reactionary, in that it celebrates what it regards as being characteristically female ways of experiencing the world and strives to correct what it regards as a masculine bias that excludes distinctive female experience. I have only read about it in the field of ethics, where feminist thinkers have criticized traditional moral philosophy as being gendered in respect of being overly abstract, overly concerned with justice (rather than "care"), reliant on an excessively atomistic, non-relational account of the self, and on an account of rationality unhelpfully divorced from the "love's knowledge" supplied by emotional engagement.
Names associated with it are Nel Noddings, Sara Ruddick, Carol Gilligan (none of whom have I read
). The woman I have read and admired whose thought seems to strike a chord with that critique is Martha Nussbaum, but afaik she does not present the critique specifically as a feminist one, although I think she writes in an explicitly feminist voice in her work on distributive justice.
