The relationships of feminist anthropology with other strands of academic feminism are uneasy. By concerning themselves with the different ways in which different cultures constitute gender, feminist anthropology can contend that the oppression of women is not universal. Henrietta Moore argued that the concept of "woman" is insufficiently universal to stand as an analytical category in anthropological inquiry: that the idea of 'woman' was specific to certain cultures, and not a human universal. For some feminists, anthropologist Michelle Rosaldo wrote, this argument contradicted a core principle of their understanding of relations between men and women. Contemporary feminist anthropologist Marilyn Strathern argues that anthropology, which must deal with difference rather than seeking to erase it, is not necessarily harmed by this disagreement, but notes nonetheless that feminist anthropology faces resistance.
