I'm just pointing out that Sakura not ending up with Naruto had nothing to do with Hinata, but with her not seeming fickle. See, there's a common thing in manga/anime, it's basically loyalty+friendship is literally magic. For Sakura to give up on Sasuke, when she spent 693 chapters being seemingly in love with him, that wouldn't be seen as a good thing. When it comes to the genre, that is. I don't understand why people are upset it's not realistic. This is a story about magical ninjas, where a man sexually harassing women is seen as charming and cute, where it's totally acceptable to train children how to murder people. Sexism has always existed in Naruto, too. I was kind of shocked people only realized it now? lol
I'll be honest, Kishimoto's statement doesn't surprise me. Manga/anime is not a great place to look for positive Western interpretations of women. Sasusaku is also a pretty popular trope there, actually. You'll find a lot of Shoujo stories where a cold/heartless person ends up warming up to the main lead, despite trying to assault/murder her.
This paralallel you made with the shojo stories doesn't work
In the shoujo stories, the guy usually has some feelings for the girl, and she actually plays a role in bringing the guy back from his dark place
Sakura didn't even played a role in bringing Sasuke back, it was all Naruto. And also there was zero indication he cared for sakura as more than a teammate,even in part 2 getting close to kill her or let her die 5 times
And yes, Sakura could have been seen as fickle after 693, but in early shippuden kishimoto already had shown signs he was considering sakura as a pair to naruto. Something changed his mind however and he kept playing the pairings until nh was ultimately decided
