In a relatively rare act of deference, in Wisconsin v. Yoder, the Supreme Court agreed the state interest in the education of children was not superior to belief by the Amish that they should remove their children from school after the 8th grade. More often, such deference has not been shown. In Employment Division v. Smith, the Court did not respect the rights of members of the Native American Church to use the controlled substance peyote, a religious practice that predates the United States. If we expect people to be true to their conscience, we must accept that sometimes religiosity informs that conscience. This represents healthy respect for plurality in a democracy.
Some people are thoroughly spiritual.
They cannot and ought not be asked to separate the core of what they are in exchange for the right to be seriously listened to in the public square.
