A nonprofit religious freedom organization is providing tools for parents to help them opt out of public-school LGBTQ+ instruction, curriculum and materials after the Supreme Court’s landmark ruling on Friday.

The Supreme Court has sided with religious parents who want to pull their children out of the classroom when a public school lesson uses LGBTQ storybooks.

The decision reverses lower-court rulings that had favored the Montgomery County Public Schools, located in the Washington, D.C. suburbs, and marks a significant victory for religious rights advocates.
