I know there's some validity to the rad-fem concepts; there are inequities in society that permeate all aspects of male/female relationships. And certainly, it's worth considering that some slash is written by women who think "men are more interesting than women."
What I can't figure out is what she wants to happen as a result of her diatribe. Does she think women should stop writing slash (or any other type of writing that she finds patriarchal)? That straight, married women should agree that their husbands are probably rapists? That women who are questioning and exploring their own sexualities should listen to her, not their own bodies, to decide what's right for them?
As far as I can sort out from her & allecto's posts, all non-lesbian sexualities are wrong (and some lesbian ones are wrong, if the women are only turning to each other because they think they're not good enough for men.) I think she's trying to claim that all physical, real-world eroticism is oppressive, and women's true sexuality is mostly "spiritual," but she hasn't put that into words. (At least, not in this post.)
(I am watching the reactions, though. I sometimes get reactions that sound similar. This helps me know when I've gone off the deep end on some wingnut theory of How The Universe Works. Which doesn't mean I'll change my wingnut theories, but I'll at least have a better idea of which ones they are.)
