The South Lyon Community School District is standing behind its decision to suspend a middle school teacher for playing a popular hip-hop song about being gay during class, even as scrutiny grows from gay advocacy and civil liberties groups. The district said teachers must preview taped material intended for classroom use, then submit a form describing the clip to a building administrator for approval, and that Johnson did neither. "The clip had no relationship whatsoever to the instructional class content planned for that day," the district said. "The purpose of this established practice is to ensure that instructional materials are appropriate for the course and its students." The American Civil Liberties Union is reviewing the incident.
