Why was Neil gaiman banned?

Neil Gaiman's works have faced bans primarily due to their themes, which some consider inappropriate for younger audiences. Books like "The Sandman" and "Coraline" have been challenged for their supernatural elements, dark themes, and perceived promotion of witchcraft. Critics have argued that these elements may conflict with certain cultural or religious beliefs, leading to calls for their removal from libraries and schools. Despite the controversies, Gaiman's works are widely celebrated for their creativity and depth.
