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.

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 Supreme Court’s conservative majority is signaling support for the religious rights of parents who want to remove their children from classes using storybooks with LGBTQ characters.
