Well, This has been off topic. You're suppose to tie the topic of western identity politics to Naruto/Boruto/Japanese anime somehow. *Shrug*, anyways.
Depends on how you view it.
We could talk about sexism in Naruto and how two cultures clash while being grossly hypocritical. You want strong female independent characters that are also subservient, highly sexualized, and completely relying on the person they are married to to the point that THAT is their defining trait?
We can talk about how appealing to a minority breaks a story and ends up coming off shallow.
The thing happening with Marvel is that your have a bunch of people that have enter the industry through thing like HR, Community Managers, Assistant Editors, and Writers & Artist. That don't like comics. But they see it as a way to get into hollywood and make their mark on culture; since Marvel has become the Biggest Movie Franchise since 2008. So they infiltrate, bring in friends, gate keep and so on in order to control the industry so they can change it to their liking. the thing is since they only care about how many characters their are that are filling their check-boxes of tolerance they don't care about the quality.
Seems like what Kishimoto is doing, but with romance. He said he doesn't do romance and he didn't care about Hinata and tried to make Sakura better, but he kept listening to the fandom that hated Sakura because she was a threat to Hinata. He should have spent his time making the story he wanted to tell and letting Sakura be herself instead making the fans insist how she had to be. (Wait, that gives me a thought...)
Hinata should have learned to be stronger without Naruto and really developed her character how true love is letting the one be happy even without you. Or she should have been taken out period. instead of giving her fandom all moments that in the end it meant nothing because Naruto didn't even realized it.
Miles is actually an odd case; he is an example before this all happened and was initially done well. He was from the Ultimate Universe where his world's Peter Parker died when he was still a teen, years later Miles took up the role; which a major part of his character was dealing with carry on the legacy of a dead teen hero, eventually the Ultimate Universe ended but they didn't want to kill off their Black Spider-Man so they brought him to the main universe. Where he has pretty much drifted since because they haven't added to his character, address the change in world would effect his story or introducing him into other media without going into detail about being from another universe, won't change it, nor give him a new identity. Also he pretty much just their black boy character if they need one to be political now.
He was a good idea turned into the token propaganda.
