Christian conservative Linda Harvey is warning parents to protect their children from “homosexual indoctrination” at school.

Harvey, the founder of the Columbus, Ohio-based Mission America and a frequent contributor to the conservative website, attacked gay-straight alliance clubs, which work to end homophobia and transphobia in schools to create a safe environment, as promoting “homosexual perversion.”

“Don't let schools get away with homosexual indoctrination,” she told her radio listeners. “You children's physical, moral and spiritual future is at stake.”

“These clubs too often end up as on-site promoters of homosexual perversion,” she said.

Parents also need to watch out for “wild liberal” teachers whose math lessons “normalize deviance,” she said.

“Not all teachers are wild liberals but quite a few are. And they get creative at getting the issue of homosexuality and gender confusion in front of children. In math, kids will face word problems that somehow incorporate same-sex parents as if this is no big deal. They'll quickly move on, no questions allowed, smoothly normalizing deviance,” she added without offering any evidence.
