The Harry Potter series has been banned in some schools and public libraries because some parents and religious leaders believe that the books promote witchcraft and wizardry. Some parents and religious leaders also believe that the books are too dark and violent for children.
Some people believe that the books are anti-family because they promote a world where children are raised by wizards instead of parents. Some people believe that the books promote a religion other than Christianity, such as Wicca or paganism.
Some people believe that the books are racist because they promote a world where people with magical powers are segregated from the rest of society. Some people also believe that the books promote white supremacy by portraying non-white characters as inferior to white characters, who are usually portrayed as heroes or villains.
In fact, there is even an entire website dedicated to documenting instances of racism in Harry Potter fanfiction.
Some people believe that the books are sexist because they portray women as weak and subservient to men. The only time you see women wielding any real power at all is when they’re doing things like being evil witches or evil enchantresses (which isn’t exactly empowering).
