Then maybe you need to read this, which was written by a modern Wiccan, decrying the rape of children.

While the article only mentions sexual abuse and rape of children, scholars do remain divided on whether the traditions of Samhain, as practiced by ancient pagans, included child sacrifice.
It is difficult to locate a pagan religion anywhere on the Earth that did not practice child sacrifice.
While there are no Wiccans flying airplanes into buildings and openly threatening to destroy Western Civilization, I would never trust any of them with any of my children.
