During an argument Tuesday, the Supreme Court’s conservatives strongly suggested they would extend religious liberty rights to parents with children in public schools.

The Supreme Court weighed whether parents can opt kids out of LGBT-themed books, bringing justices to debate religious rights, school policy, and limits of exposure.

The U.S. Supreme Court appeared inclined to rule in favor of Christian and Muslim parents in Maryland seeking to keep their elementary school children out of certain classes when storybooks with LGBT characters are read in the latest case involving the intersection of religion and LGBT rights.
