Perhaps in this fanfiction, Akeno is associated with an enemy group or ideology that Naruto is opposed to. He has strong beliefs, and if she represents something he fights against, it would make sense for him to hate her.
Perhaps in the fanfiction, the village fails to protect the people he cares about. Maybe his friends get hurt or killed because of the village's negligence or wrong decisions. That would be a strong reason for Naruto to hate the village. Also, if the village's leadership becomes corrupt in the fanfiction and starts treating the people unfairly, including Naruto, it could fuel his hatred.
In some fanfictions, Naruto might be depicted as hating shinobi due to feeling betrayed by the shinobi system. Maybe he witnessed too much corruption or hypocrisy within the shinobi world that made him lose faith in it.
There could be several reasons. Artemis might be a purist when it comes to the Naruto universe. Fanfictions often introduce new elements or change existing ones in ways that she doesn't approve of. Also, if she has read a bunch of poorly written Naruto fanfictions, it could have turned her off completely. She might expect a certain level of quality in storytelling, and when fanfictions don't deliver that, she develops a dislike for them.
Maybe it's because of the hardships Naruto endured due to Minato's actions. Minato's decision to seal the Nine - Tails in Naruto made him an outcast. In fanfiction, this could be exaggerated to the point where Naruto blames Minato for all his pain and suffering, leading to hatred.
It could be that she simply doesn't like the quality of most Naruto fanfiction. A lot of fanfiction out there is poorly written, with bad grammar, inconsistent plotlines, and out - of - character portrayals. Ayame might be turned off by these common flaws in Naruto fanfiction.
Maybe in some fanfictions, the writer wants to create a new plot where Naruto has some misunderstandings about Jiraiya. For example, if Jiraiya made a decision that Naruto thought was wrong regarding the village or his friends, it could lead to Naruto hating him in that fictional scenario.
Maybe he hates it because it often distorts the original story. Fanfictions might take his character or Naruto's in directions that he wouldn't approve of in the original Naruto universe.
It could be that the cultural aspects of Christmas don't resonate with Naruto's character in the fanfiction. He comes from a different cultural background in the Naruto world, and the whole idea of Christmas - the gift - giving, the Santa Claus, etc. might seem strange and unappealing to him. So, the writer of the fanfiction might have decided to make him hate it for that reason.
Perhaps in certain fanfiction scenarios, Naruto discovers some dark secrets about the shinobi world that make him lose faith in it. Like the hidden political machinations that sacrifice the innocent. This realization could make him hate the world he once fought to protect.
It could be that he believes fanfiction sometimes goes against the intended spirit of Naruto. Fanfiction might include elements that he doesn't approve of, like changing the characters' personalities in a way that he thinks is wrong. For example, if a fanfiction makes Naruto overly mean or out of character, Iruka, who has a deep understanding of Naruto's true nature, would dislike it.
