Are there any non-realistic fiction books banned and why?

Realistic fiction books could get banned if they go against the moral or ethical standards of a particular society or if they promote harmful behaviors.

Some are banned because of their language. For instance, if a book contains a lot of swear words or vulgar language, it might be considered inappropriate for certain audiences, like young readers. So it gets banned in some places where there is a more conservative view on what can be read.

One reason could be the presence of disturbing content like abuse. For example, if a book graphically depicts child abuse, it may be banned to protect children from being exposed to such traumatic material.

I'm not sure specifically which books are on such a list as it can vary by different regions, schools or organizations. However, some books might be banned due to containing controversial topics like violence, or themes that are considered too mature for children in certain cultural contexts.

One example is 'The Catcher in the Rye'. It has been banned in some places due to its use of profanity, sexual references, and the portrayal of a somewhat disillusioned and rebellious adolescent. Some parents and educators thought it was not suitable for younger readers as it might influence them in what they considered a negative way.

Some historical fiction books are banned because they contain controversial themes. For example, if a book portrays a certain historical event in a way that challenges the established view or makes a particular group uncomfortable. If a book shows the darker side of a nation's history, like the oppression of a minority group, it might be banned by those who don't want that history exposed.

Some horror fiction books can also be banned due to religious or cultural sensitivities. If a book contains elements that are offensive to a particular religious group or goes against the cultural norms of a community, it may be banned. For example, a horror book that mocks or misrepresents religious beliefs or practices might face such a fate.

Books in adult fiction are sometimes banned because of their sexual content. For example, if a book contains detailed and explicit descriptions of sexual acts, it may be considered inappropriate for the general public. This was the case with 'Lady Chatterley's Lover'.

Some historical fiction books might be banned because they contain inaccurate or misleading information that could distort history.

One famous example is 'The Catcher in the Rye'. It was often banned because of its use of vulgar language and its exploration of teenage angst and alienation in a way that some considered inappropriate for young readers. Another is 'Lolita' by Vladimir Nabokov. This was banned mainly due to its disturbing theme of an adult's sexual attraction to a minor, which goes against moral and ethical norms in most societies.
