However, the quotes you choose are from a section that notes that "Various feminist standpoint theories ground the claim to epistemic privilege in different features of women's social situation" -- and in a paragraph starting with "Some early versions of standpoint theory (including Flax 1983, Hartsock 1987, Rose 1987, and Smith 1974) accept feminist object relations theory ..."
So I'd caution against rejecting the whole discipline based on early views from a handful of a few people.
