(WNS)–Fifty-one families from the Chicago suburbs are saying “enough” to the Obama administration forcing schools to let boys and girls who identify as the opposite sex use the restrooms of their choice. The families, represented by Alliance Defending Freedom (ADF) and the Thomas More Society, filed a suit against the U.S. Department of Education in federal court May 4. The lawsuit claims the department is “continuing to trample students’ privacy and other constitutional and statutory rights” in its enforcement of Title IX, a law that prohibits gender discrimination in federally funded schools. In April 2014, the Department of Education’s Office of Civil Rights (OCR) ruled Title IX protections cover discrimination on the basis of gender identity as well as biological sex. Since then, schools around the country have faced threats of having their federal funding revoked if they don’t meet the demands of transgender students.
