I've heard several interviews with the exorcist for the archdiocese of NY. He states that playing with ouija boards, holding seances, and the like has opened the door to the occult for many children, paving the way for demonic obsession or oppression. I believe I would rather my child play with a Ouija board than be buggered by his parish priest in the sacristy after Mass. But that's just silly little ol' me.
