I do hate Tyrion. Greatly. But it was actually when Cersei got her own POV chapters, apart from Tyrion, that made me disgusted with her. How she was constantly wishing rape on other women (and thinking that they'd "appreciate" it). That is something I can't tolerate. It's not just questionable for me at that point. Also, she starts abusing her own children which is another trigger issue for me. I cannot deal.

And it bothered me on an authorial level that Cersei wanted power so that she could be "like a man". Not for herself, but to become a man, because that obviously was the most important thing. She didn't value herself as an ambitious woman, but only as a woman-trying-to-be-a-man. Literally. Which seems like such an anti-feminist concept (and she uses it to oppress other women in the book) that I just can't deal with it, on top of her rape-apologetics and child abuse. I went from completely loving her to completely hating her.
