A case developed for courses in leadership education--particularly for those centered in social justice and ethical leadership--is described. Students test their own assumptions about "difference" and are called on to make leadership responses that are grounded in ethical frameworks. This case highlights tensions that surround lesbian, gay, bisexual, and transgender students in increasingly diverse school settings. The story is revealed through the eyes of a principal who must turn a negative response to a Gay-Straight Alliance event to one that fosters school and community discussion on inclusiveness and demonstrates the power of advocacy.
