Too much about race and gender is injected into opinions about this show based on people's real world perceptions and agendas. It's a fantasy show in a fantasy world. It's also set in a medieval time period where things like equality and social justice are at the bottom of the priority list, if they are even on the priority list. Bran didn't get the throne because he's a white guy. The person who either sat on the throne herself or controlled it when her children sat on it for seven out of the eight seasons was a woman - Cersei. One of the seven kingdoms is Dorne, which is the Westeros version of an Arabic culture. The show itself was never about addressing race or gender issues, and it was never the responsibility of the show to do that. Westeros didn't need to reflect our real world 21st century values, nor should it. If people want that sort of thing, there are a lot of shows out there which cater to that.
Sansa was raped. It happens. In a medieval world like Westeros, it would happen a lot and be tolerated and even acceptable in places. Lots of shows depict rape and get lauded for it. GoT does it and it's misogynistic. Sansa said it was thanks to Ramsay Bolton and others that she is who she came to be. It wasn't a thank you to Ramsay Bolton, there was no admiration when she said it. She followed that statement by describing what she did to him in the end. Was GoT saying that a woman has to be raped to become strong and a leader? No. Arya wasn't raped. She turned into a deadly assassin. Cersei didn't become Queen of the Seven Kingdoms by being raped. Yara didn't command the Iron Fleet because she was a victim of abuse. Sansa wasn't like them, though. She was a wallflower who couldn't stand up for herself. She had no backbone. It took a severe trauma to change who she was. It also seems to be forgotten that Ramsay Bolton did even worse to Theon, a male. So what happened to Sansa wasn't about gender at all, it was about abuse at the hands of a sadist. And both her and Theon's stories were about rising above what he did to them and becoming something better.
