First, examine the world - building. 'Harry Potter' has a detailed and unique world of magic with its own rules and institutions. Then look at the plot. It's about a young hero's quest to defeat an evil wizard. There are no elements from the 'Lucifer' concept in any of this. Also, the moral and ethical undertones in 'Harry Potter' are different from what one would expect in a 'Lucifer' - related story. So, it's clear that 'Harry Potter' is not 'Lucifer' fanfiction.
By simply looking at Harry's actions. He constantly tries to save people, like when he saved Ginny from the basilisk in 'The Chamber of Secrets'. A psychopath wouldn't care about others' well - being like that.
We can disprove it by examining the key elements of the Harry Potter story. The story revolves around Harry's life at Hogwarts, his friends Ron and Hermione, and their adventures in the wizarding world. There are no vampire - like characteristics or storylines in it. The magic in Harry Potter is based on spells, charms, and the use of wands, which is very different from the typical vampire - related themes.
We can disprove it by simply looking at the source material. The books are full of positive elements like the fight against bigotry (e.g., the treatment of Muggle - borns) and the importance of loyalty among friends. There's no room for any perverted ideas in these plots.
By simply looking at the origin and development of the 'Harry Potter' series. J.K. Rowling created it independently with her own ideas and creativity. There's no evidence of it being based on 'Mormont' fanfiction.
Just play the game. The moment you start, you'll see that there is a clear narrative arc. You start as a character with a certain set of circumstances and as you progress, you uncover more about the world, the characters, and the overarching plot. So, playing it disproves the claim.
First, examine the themes. Harry Potter is about growing up in a magical world, facing evil in the form of Voldemort. Stargate is about exploration and dealing with alien races. Also, the timelines of creation are independent. So, it's clear Harry Potter is not a Stargate fanfiction.
One can simply point out that 'Harry Potter' was created by J.K. Rowling. It has a clear origin and development process that is completely different from fanfiction. Fanfiction is built on existing works by fans, while 'Harry Potter' is the foundation for a vast amount of fan - created content, not the other way around.
One way to interpret it is by looking at the moral themes. The battle between good and evil in Harry Potter can be seen as similar to the moral struggles in Jewish teachings. The idea of standing up against injustice, like Harry and his friends do against Voldemort, is a key value in Judaism. Also, the community aspect of Hogwarts, where everyone supports each other, is somewhat like the Jewish community. However, this is a very broad interpretation and doesn't mean it was written as such.
By pointing out that J.K. Rowling created the entire 'Harry Potter' universe from scratch. She came up with the idea of Hogwarts, the characters like Harry, Hermione, and Ron, and all the magical elements. It's a fully - fledged original work, not something based on someone else's work as fanfiction is.
One can simply point out the positive themes in 'Harry Potter'. It's a story of heroism, not crime.
