"The fact that they argue in this vein indicates that it is often gays and lesbians who are most often the targets of this abuse, and that's why it's doubly important to protect them."
Focus on the Family takes particular issue with recent curricula adopted in Alamdea, Calif. The school board there last year adopted an anti-bullying program for elementary school students that specifically mentioned gays and lesbians.
The Colorado-based organization says the Gay, Lesbian and Straight Education Network has targeted thousands of school districts nationwide with literature. "Schools are only allowed to provide one message about homosexuality; that it's normal and should be embraced," Focus on the Family said of the gay group's message.
"The school introduced anti-bullying lessons but really they're teaching elementary school kids about gay marriage," Cushman told ABC News.com. "We think parents should have the right to teach kids about it in their own way."
The Gay, Lesbian and Straight Education Network says its anti-bullying campaign was created with input from educators, psychologists and even members of religious organizations, and its goals are distinct from its support of same-sex marriage.
The group, however, does not deny that there is mention of same-sex marriage in some of its anti-bullying literature.
Some parents who advocate for anti-bullying legislation and are conservative Christians say they are torn between seeking the most programs in the most places and avoiding mention of homosexuality in the classroom.
"I am a Christian. I am conservative. Some would call me right-wing," said Brenda High, whose son, Jared,committed suicide in 1998 when he was 13 after being routinely bullied and beat up at his Washington state middle school.
"The problem is our schools are not teaching kids to become responsible adults. When you allow kids to call people names or bash them because they think they might be gay and make assumptions and judge people, that's when kids get hurt.
"There's nothing wrong with a little religion: Teach them the Christian idea 'to do unto others,' everyone gay or straight, any religion, even atheists agree with that one," she said.
