As religions go, Wicca is usually pretty inoffensive. Wiccans are a small minority of the population, don't proselytize, and generally don't bother others. But they just got some major bad publicity.
A woman who claims she was going to perform a Wiccan celebration of spring is accused of using a ritualistic dagger to kill a man she invited to the ceremony.She's claiming self-defense, but police don't believe her story of attempted rape. And apparently her account was inconsistent.
What are the odds that some Christians will use this incident to reinforce and promote superstition about witches, Satan worship, and human sacrifices? This woman didn't just kill someone, she may have done considerable damage to Wiccans all over, who already have to fight against the superstitious view of witches popular with many Christians.
