Parents and physicians are suing the Clovis Unified School District near Fresno, California, over its high school abstinence-only sex education, according to a statement by the American Civil Liberties Union (ACLU), which represents the plaintiffs. The lawsuit claims the district is violating state law, as well as putting the health of teenagers at risk. The ACLU says the textbook used by the district does not mention condoms, but instead lists abstinence, self-respect and plenty of rest as ways to prevent sexually transmitted infections. The ACLU asserts that this suit is the first of its kind in California.
