Just reading a news item on CNN about albinos being killed for their body parts.
"In some African countries, albinos' body parts are believed to bring wealth and good luck. As a result,attackers chop off their limbs and pluck out organs, and sell them to witchdoctors."

While the people who practice this slaughter are extremists and few in number, they are driven by the same religious fervor that causes a few extremists elsewhere in the world to destroy their own families over one's questioning of the Watchtower governing body.
