The U.S. Supreme Court on Friday agreed to consider the constitutional rights of religious parents to prevent their children from reading LGBTQ-themed books in elementary public school.

The court granted certiorari in Mahmoud v. Taylor, a lawsuit challenging the Montgomery County, Maryland, school board's stance on parental opt-outs for LGBTQ-themed books. The case is the latest in a string of religious liberty disputes to reach the Supreme Court, whose conservative supermajority of Republican appointees has frequently sided with religious litigants bringing claims under the Free Exercise Clause of the First Amendment against various governmental entities, from school districts to civil rights commissions.
