Why is the book Halloween ABC banned?

It's banned in some American states for being frightening, violent and generally unsuitable for children.

It was also banned in some American states for "being un-Christian" which has caused uproar all over the globe - even by Christians themselves who claim the banning was unnecessary.

Preventing people from accessing arts and creativity - such as books - (which do not violate the law) is also a violation of the international Human Rights Act.
