African children accused of witchcraft abused, cast out, even killed by own relatives, including parents

See this NY Times article about this tragic happening in Angola, Congo, and Congo Republic:

The churches promoting belief in witchcraft are Christian. Take a look at the pictures. As the article explains, the real reason behind parents accusing their children of witchcraft and then throwing them out to fend for themselves on the streets is poverty. Believing their child is a witch gives them an excuse not to care for the child. Cultural disintegration is on display here at a truly low level, and religion is playing a huge role in that disintegration. I realize the one Catholic church and its bishop cited in the article are trying to help some of these children, but how much is the world Catholic church and its stance against birth control and sex education to blame for causing the situation--large families with unwanted children--in the first place? This is what fundamentalist and Catholic Christian missionaries have wrought in Africa, a horrible blend of their superstition with existing Bantu superstition, both of which include belief in witches. Angola, Congo, and Congo Republic are living in a medieval world in the 21st century.
