She's basically suggesting a revisiting of some of the assumptions feminist thought has made in the past, in light of the outcomes of those assumptions.
One of her major ideas that informs a lot of her assessments is that the idea of progress as such is a misunderstanding of how society works, there is no movement towards some better and better end, much less an ideal end.
Rather, social rules, laws, political structures, and institutions, represent attempts for a society to function effectively within a certain set of constraints. Those constraints may be fairly constant in some cases, like human nature, human reproduction, the necessity to feed ourselves, raise children, care for the elderly. Or they may change, like technology, available economic capital or infrastructure. What might be a workable solution in one environment will not be in another, and when the environment changes, systems that may have worked in the past may no longer work.
She also says that in many cases, these arrangements involve trade-offs, and it's important to acknowledge what those are.
