I don't believe in the devil, and I don't think, even if there are spirits that/who would like to communicate with us, they'd need to resort to going through a toy that is manufactured by - who - Parker Brothers? Milton Bradley?
To me, it just doesn't make sense that if there are spirits "out there" they'd need to resort to sending their messages through something man-made, like a Ouija board. Surely, if they exist, they have some way to send messages other first hoping some fourteen-year-old digs a Ouija board out of a basement and then using the alphabet. It just seems to me that if they exist they're probably more "advanced" than that.
