I have to correct all now

Pentacle

"A real popular symbol used by many that dabble in the occult. Many pagans such as those who practice wicca and other forms of witchcraft wear the emblem as a pendant. Some even go as far as placing them in all the rooms of their homes, especially during pagan holy days such as: Christmas, Easter, Father's Day, Mother's Day, New Years Day, Thanksgiving Day, Valentine's Day, and last but not least, Halloween."
Pentagram

"Another rendering of the popular symbol, only inverted. Today, the pentagram may be even more common than the upright pentacle. Satanists, a more sinister breed of the underworld usually wear this symbol as a pendant or use this symbol in satanic rituals. It is found at many sites where sacrifices and other rituals have taken place. It is also found as art work on many Satanic heavy metal albums such as Slayer."
Whole bunch of other stuff too.
