I generally think it's impossible to live in a patriarchy and not have some form of internalized misogyny (even while being aware of all the dynamics of patriarchy and feminism and how they interact.) And Cersei's world is a lot more misogynistic and problematic than our own, with no benefit of feminism and women's right movements. I don't think I can blame her much for hating her gender or hating other women. It just makes me feel sorry for her, but it's...understandable?

Honestly, everything I have read about Cersei makes me just think that I am going to probably end up understanding most of her choices and wanting things to be better for her so she could, um, make better choices. And possibly hating the writer a lot for making Cersei unsympathetic.
