Maybe he finds them too obsessive. In fanfics, fangirls might be portrayed as constantly crowding him, not respecting his personal space, and only being interested in his looks or status as a hero. This could make Naruto, who values real connections and his own growth, dislike such fangirls.
Well, it could be that Kakashi, being a character who values the integrity of the original Naruto narrative, sees fanfiction as a deviation. Fanfiction might include out - of - character scenarios for him or the other characters. He might also dislike the fact that some fanfictions can be of very poor quality in terms of writing and plot, which could be a reason for his dislike.
Well, it could be that in some fanfictions, the writers might portray Artemis in a way that goes against Naruto's values. Maybe Artemis is depicted as too cold or having actions that Naruto, with his warm - hearted nature, simply can't stand.
It could be that she values the authenticity of the original Naruto story. Fanfictions often introduce all kinds of wild ideas and concepts that she might find disrespectful to the carefully crafted world of Naruto. For example, some fanfictions might change the relationships between characters in a way that goes against her understanding of the Naruto universe.
In some fanfictions, Naruto might be depicted as hating females due to a misinterpretation of his character. Maybe the author wants to create a unique and edgy storyline. For example, they could be trying to show how a past bad experience with a female character, like being rejected or betrayed by one, has turned him bitter towards the whole gender in their fictional version.
In some fanfics, Boruto might be depicted as hating Naruto because of the lack of attention he gets from his father. Naruto is often busy with Hokage duties, leaving Boruto feeling neglected.
In some fanfictions, Naruto might be depicted as hating Konoha due to feeling betrayed. For example, if the village turns against him unjustly or fails to support him when he needs it most. Maybe they suspect him of something he didn't do, like being involved in a crime against the village, which could lead to his hatred.
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.
Maybe he thinks fanfic often distorts the real story or characters of Naruto. In the original Naruto series, Kakashi has his own understanding and relationship with Naruto. Fanfic might create some scenarios that go against his view of Naruto or the world they live in.
Well, in fanfic, the writer can take creative liberties. It could be that Naruto has grown and evolved in a different way than in the original story. He might have seen Sakura's flaws more clearly over time. For example, her obsession with Sasuke could be seen as a negative trait that affects the team dynamic. And as Naruto values the team highly, this could cause him to develop a dislike and eventually hate for Sakura.
