One reason could be that Naruto values respect, especially towards women. Perverts in fanfiction might go against this value of his. He has been shown to be protective of his friends, and seeing improper behavior towards them or others in fanfiction would make him dislike it.
Naruto is a character who has been through a lot and has developed his own moral code. In fanfic, perverts might engage in actions that are inappropriate or immoral. Naruto, having seen the hardships in his village and the importance of integrity, would not be fond of such characters. He is the type to uphold good values and fight against those who violate them. Fanfic perverts might act in ways that are contrary to what Naruto stands for, like objectifying others or being overly lewd, which is why he would hate them.
Fan artists could draw Naruto with expressions of anger or disappointment when in the presence of pervert - inspired situations in their artworks. This visually conveys the idea that he hates such fanfiction. Another approach could be in the dialogue. Writers can write dialogues where Naruto voices his strong dislike for pervert - related fanfiction, perhaps comparing it to something that goes against the ninja way.
In some fanfics, the idea of Naruto hating Hinata might be a plot device to create drama. Maybe the writer wants to explore a different kind of relationship dynamic than the canon one. It could also be that the writer has a unique interpretation of the characters' personalities and how they might clash in certain situations.
Maybe it's because Aphrodite's powers and the way she uses them are at odds with Naruto's own beliefs. Naruto believes in self - improvement through training and facing challenges head - on. If Aphrodite uses her love - related powers in a way that seems unfair or goes against Naruto's sense of justice in the fanfic, he would dislike her. Like if she uses her powers to manipulate people's emotions for her own gain, which is something Naruto would oppose.
The idea of 'pokemon perverts fanfic' is highly unethical. Pokemon is a franchise aimed at a wide range of audiences including children. Fanfics with perverted content violate the family - friendly and positive nature of the Pokemon world. It can also be considered a form of inappropriate and disrespectful use of the intellectual property.
Well, it could be that Naruto has been betrayed too many times. Maybe he discovers that some of his closest friends have been using him all along for their own gains. So he starts to hate everyone, and the story could be about his journey of isolation and self - discovery as he tries to come to terms with his new feelings.
Often in these fanfics, Sakura might make fun of Naruto's dreams or goals in a very mean - spirited way. This constant put - down could lead Naruto to hate her. Also, if Sakura were to side with Naruto's enemies in the fanfic for some reason, like being brainwashed or having a hidden agenda, it would be a likely cause for Naruto's hatred.
One possible storyline could be that the Si OC is a shinobi from a village that has been wronged by Konoha in the past. They see Naruto as a symbol of Konoha's power and thus direct their hatred towards him. For example, if their village was raided by Konoha in the past for some reason, they hold a grudge against all things Konoha, including Naruto.
It could be Naruto himself. Since he hates everyone, his actions against the people he once cared about could make him the antagonist. He might start attacking the Hidden Leaf Village or other ninja villages, making him the main source of conflict.
