Banned in Ireland (1932). Removed from classroom in Miller, MO (1980), because it made promiscuous sex "look like fun" and challenged frequently throughout the U.S.
Challenged as required reading at the Yukon, Oklahoma High School (1988) because of "the book's language and moral content."
Challenged as required reading in the Corona-Norco, California Unified School District (1993) because it is "centered around negative activity." Specifically, parents objected that the characters' sexual behavior directly opposed the health curriculum, which taught sexual abstinence until marriage. The book was retained, and teachers selected alternatives if students object to Huxley's novel. Brave New World was again challenged in Foley, Alabama (2000) because of the depictions of "orgies, self-flogging, suicide" and characters who show "contempt for religion, marriage, and the family." The book was removed from the library, pending review. Source: 2001 Banned Books Resource Guide.
Book banners have cited "negative activities" (undoubtedly referring to the sex and drugs) in the book as reason enough to prevent students from reading the book. [I guess the children's sex games could be included in that... lol.. and being punished for not playing the sex games... oh boy]
