Maybe because they are a big fan of the original 'Harry Potter' series and are tired of seeing really bad fanfiction. They want to emphasize that the real 'Harry Potter' is much better than those poorly - made versions.
It could be that the person saying it has a deep respect for the original work of J.K. Rowling. They see the 'Harry Potter' series as a masterpiece with its own rules and aesthetics. When fanfiction doesn't meet those standards, whether it's in terms of writing quality, respecting the magic system, or character development, they feel the need to make this statement. They want to protect the integrity of the 'Harry Potter' universe from being diluted by bad fan - made stories.
I think it means that the 'Harry Potter' world created by J.K. Rowling is so rich and well - defined that it doesn't need to accept or be associated with bad fanfiction. Fanfiction can vary greatly in quality. Some might distort the characters or the magic system in a way that doesn't do justice to the original work. So, it's like saying the real 'Harry Potter' is too good for that.
Maybe it's a way of stating that the integrity of the original Harry Potter character is not influenced by fanfic. Since fanfic can sometimes deviate greatly from the original source, saying 'harry potter doesn't care fanfic' is like saying the original character remains untouched by these fan - created ideas. Fanfic often has different interpretations of characters, and this statement could be a way to uphold the original view of Harry Potter.
Perhaps they don't fully understand the depth of the world - building. They might see all the magic and think it's just some random, crazy ideas thrown together like in a not - so - well - thought - out fanfic.
Perhaps they haven't fully understood the series. Some people might just skim through the books or movies and miss out on the depth. They could be focusing on just the surface elements like the magic spells and not realizing the complex relationships and themes beneath.
Perhaps they've come across some really strange fan - created stories. Some fanfictions can be very out there with their interpretations of the wizarding world.
Maybe they want to emphasize the purity of the original 'Harry Potter' story. They don't want it to be confused with the many fan - made stories out there.
One reason could be that they feel the official Harry Potter story has a defined end, and the fighting in fanfiction is just over - done. They want to focus on the original tale's conclusion.
Maybe they just want to be controversial. Some people like to make extreme and untrue statements to get attention.
Maybe in the fanfiction, Harry has no interest in divination. He might be more focused on other subjects like Defense Against the Dark Arts or Quidditch.
Maybe they just don't understand the real essence of Harry Potter. They might have only seen a small part of it or misinterpreted some of the more emotional or character - developing moments as signs of weakness, which is completely wrong.
