The ACLU has filed a lawsuit to force a Utah school district to keep a lesbian advocacy book on elementary school library shelves, LifeSiteNews.com reports. A book called In My Mothers' House, about three adopted kids and their lesbian "mothers," was added to library shelves in five of the Davis School District's 50 elementary schools after administrators learned that a Windridge Elementary student was being raised by lesbians. When a kindergarten student brought the book home, a group of concerned parents brought a petition to the school asking that the book be removed. After a seven-member parent-teacher committee decided that the book would be kept behind the counter instead of on the library shelves, and that children could only check it out if their parents signed a permission slip, the ACLU filed suit to put the book back on the shelves and make it available to all children without restriction. Davis School District spokesman Chris Williams said the district stands behind its decision to require students to have parental permission to check out the book.
