While many Christians today are closely monitoring the growth and activity of Islam, especially after 9/11, another religious movement has been steadily growing “under the radar” and could become among the largest religions in the United States in less than five years. “Wicca is the fastest-growing religion in America, set to be the third largest religion by 2012,” claims Marla Alupoaicei, who co-wrote the recently released book “Generation Hex” with fellow Christian author Dillon Burroughs. “The numbers of adherents are doubling every 30 months,” she says. Furthermore, every major city in the United States has networks of Wiccans, adds Burroughs.
