People in the ASOIAF fandom are very obsessed with passive women they can project onto. The obsessions with the characters of show!Alicent, Sansa, Elia, and Helaena are perfect examples of this.
In the show, Alicent is changed from a woman who actively seeks power and heads the scheming of the green faction into a passive victim who watches and reacts to the men around her. And yet, despite this being a much more boring characterization, the show version is vastly more preferred by her stans. They condemn her book character as simply an "evil stepmother trope" while completely ignoring how their fav is just as blank and tropey as they accuse her book counterpart to be. Alicent stans want her to be the show's blank victimized canvas.
Helaena is someone who the show changed very little in the adaptation, because both book and show Helaena have little impact on the plot other than to be victims of their surroundings. Both women are forced to marry Aegon at thirteen and have his children, go through B&C, and are the least active members of the green faction. The show only added elements to make her more tragic: her dreaming and autistic behaviors. Helaena's character makes her the perfect canvas for certain fans to project themselves onto as she simply exists to be victimized and play the dutiful wife/daughter despite her circumstances, just like the show version of her mother.
Elia Martell is a woman who we know very little about. She died thirteen years before the events of ASOIAF and, unlike characters like Rhaegar and Lyanna, she has no pov characters who think about her enough for us to learn anything about her. The only things we know are that she was loved by her family, was in an arranged marriage to Rhaegar, had his two (confirmed) children, and was brutally raped and murdered by Lannister men. She is an unknown character and, again unlike Rhaegar and Lyanna, has no known active role in the events surrounding the Rebellion. Because of these things, she is, again, the perfect blank canvas for people to project on.
Sansa is, despite being a prominent pov character in ASOIAF, a very passive character. She rarely takes action in her circumstances and simply reacts to them while trying to survive. There's nothing wrong with this, she's a young girl who has never had to fight for anything in her life, it's not unexpected or condemnable for her reaction to her circumstances to be this way. However, her passivity is something her stans obsess over. She is praised for being the "perfect lady" and they project their desires to see her rule onto her and how they view her story.
These women have been chosen by these fans because of their passivity and tragedy. They love that the women have suffered in the name of the "duty" they believe is higher than them. Because they love passivity, they hate the women of ASOIAF who are active in their own lives and fight to better their circumstances. Characters like Rhaenyra, Arya, Daenerys, and Lyanna are all massive influences on the world and purposely chose to challenge the patriarchy. Since they did not take their suffering silently, theses certain fans view them as wrong and hate them. They only love the women they can project on and who simply refuse to fight for better lives.
