Among the most popular religions to have flowered since the 1960s, Wicca — a form of paganism — still faces a struggle for acceptance, experts on the religion and Wiccans themselves said. In April, Wiccans won an important victory when the Department of Veterans Affairs settled a lawsuit and agreed to add the Wiccan pentacle to a list of approved religious symbols that it will engrave on veterans’ headstones.

But Wicca in the civilian world is largely a religion in hiding. Wiccans fear losing their friends and jobs if people find out about their faith.
