Two LGBT rights groups representing three plaintiffs on Friday filed a lawsuit seeking to overturn a Utah law that bars teachers from discussing homosexuality in a positive way.

The National Center for Lesbian Rights (NCLR) and Equality Utah are representing two students who are gay and a 7-year-old former student who is gender non-conforming. Identified as John Doe in the complaint, the 7-year-old stopped attending a public elementary school after he was traumatized in a bathroom by a tormentor.

The groups claim in their lawsuit that Utah's “Anti-Gay School Law” violates Title IX of the Education Amendments of 1972, the Equal Access Act and the Equal Protection Clause of the 14th Amendment of the U.S. Constitution.

“[T]he Anti-Gay School Laws single out ‘homosexuality’ and LGBT persons for negative treatment, improperly restrict student and teacher speech about ‘homosexuality’ and LGBT persons, and create a culture of silence and non-acceptance for LGBT students and teachers, all of which puts LGBT students at heightened risk of isolation, harassment, and longterm negative impacts on their health and well-being while serving no legitimate state interest,” the 38-page complaint states.

Similar laws exist in seven other states, including South Carolina, Alabama, Arizona, Louisiana, Texas, Mississippi and Oklahoma.

NCLR Executive Director Kate Kendell called such laws “dangerous” in a statement.

“The U.S. Supreme Court has held that sexual orientation is ‘a normal expression of human sexuality’ and that LGBT people must be treated equally under the law,” Kendell said. “These laws openly discriminate against LGBT students and teachers. They stigmatize vulnerable young people who should be celebrated and supported, and they censor constitutionally protected free speech, including students’ right to receive accurate information about sexual orientation and LGBT people.”
