GenQ - For the not so straight individual

A fairy tale about gay marriage has sparked a civil rights debate in Massachusetts, after a teacher read the story to a classroom of seven year olds without warning parents first.

A parents' rights group said it may sue the public school in the Lexington, where a teacher used the book King and King in a lesson about different types of weddings.

Brian Camenker, president of the Parents Rights Coalition, a conservative Massachusetts-based advocacy group said he believes the school, Joseph Estabrook Elementary, broke a 1996 Massachusetts law requiring schools to notify parents of sex-education lessons.

But Lexington Superintendent of Schools, Paul Ash, said the school was under no legal obligation to inform parents.

As Massachusetts is the only U.S. state where gays and lesbians can legally wed.

The issue erupted in Lexington when parent Robin Wirthlin complained to the school's principle after her 7-year-old son told her about the reading. She then turned to the Parents Rights Coalition, which released a statement on the issue to Boston media last week.

King and King was ranked eighth among the top 10 books people wanted removed from libraries in 2004, according to the American Library Association.
