I would not recommend looking for it. Since 'mudblood' is a derogatory term from Harry Potter, any fanfiction associated with it in such a way might involve offensive content.
It depends on the type of fanfiction. In some darker, more edgy fanfictions that explore the extreme aspects of the Harry Potter universe, it might be more common as it delves into the power dynamics and prejudices. However, in more light - hearted or canon - compliant fanfictions, it would be less common as it goes against the general spirit of the original series which promotes equality.
Yes, there might be some fanfictions out there that explore darker or more complex storylines where such a thing could happen. However, this goes against the positive growth of their relationship in the original 'Harry Potter' series. In the canon, Ron's use of that term was a regrettable moment of weakness, and most fanfictions tend to uphold the characters' better natures.
In some fanfictions, Bellatrix screams 'Mudblood' at Hermione as a display of her pure - blood supremacist beliefs. Bellatrix, being a Death Eater, holds deep - seated prejudices against those with non - pure - blood heritage like Hermione. It's a way to demean and intimidate her.
Prejudice is a very common theme. Since Mudbloods are looked down upon in the wizarding world, many fanfictions focus on how they face and overcome this discrimination. For example, in some stories, Mudbloods have to prove themselves worthy in a world that doubts their abilities.
The term 'filthy little mudblood fanfiction' is quite concerning. Given that 'mudblood' is a discriminatory term in the Harry Potter series. Fanfiction often takes the elements of the original work and twists them. This could potentially be a fanfiction that uses this offensive term to create a story that might involve characters being mistreated or discriminated against in a fictional scenario. It might also be a work that tries to subvert or comment on the use of such a term in the original series, but again, without more details, it's difficult to determine precisely.
One common theme is the struggle against prejudice. In these fanfictions, the Death Eater often has to overcome their ingrained beliefs about Mudbloods, and the Mudblood has to face the danger from the Death Eater's side. Another theme is redemption. The Death Eater may seek to redeem themselves through their relationship with the Mudblood.
One key theme is acceptance. Ron has to fully accept Hermione's'mudblood' status, and in turn, she has to accept that he may not always understand the full extent of the discrimination she faces at first. It's about growing together in understanding.
Friendship is also a major theme. Harry and Hermione's friendship is tested and strengthened through the use of the'mudblood' concept. In many fanfictions, their bond deepens as they face the bigotry together. It shows how true friendship can overcome even the harshest forms of discrimination.
In the Harry Potter universe, 'mudblood' is a derogatory term for wizards or witches with non - magical parents. In fanfiction, 'hermione is not a mudblood' likely means that the story will not tolerate or include any plotlines where Hermione is treated as less because of her 'mudblood' status. It could be a way to rewrite or correct the often unfair and discriminatory situations she faces in the original series regarding this.
