From the grab bag of barking mad superstitious ignorance, I give you Tanzania's baby murdering witch doctoring.
Hard to believe that this savage(*) f#ck nuttiness still happens in the 21st century.
Let's face it, this is an insult to actual savages, many of whom would never imagine anything this perverted.
It is important to note that Tanzania is not completely untouched by civilisation, indeed they've had exposure to Christian ministry for centuries, and in a 2010 Pew survey 61.4% self identified as Christian. Still this obscene atrocity remains. Why? perhaps because ignorance is more profitable than wisdom.
Clearly education is the key to wiping out such backward behaviour, and there has been plenty of opportunity to make that happen. If Christianity were the force for good that Christians claim it is, then surely educating people out of this nonsense would be a high priority. But instead, especially well publicised are West and Central African nations where we find churches promoting witch persecution, often directed at children while there preachers live lifestyles that many would envy in developed nations, but clearly East Africa is not immune to the glamour of destroying children for the sake of salacious ill founded fantasies about good and evil and so doing becoming a greater evil than harms with which they are they are faced by virtue of living in a world vastly more complex than the understanding that they have been given by their culture, their religious prelates, and what ever the education system has made available to the Tanzanian population. Many have been denied education in Tanzania but poverty a school fees (fees were waved in 2001) leaving many dangerlously ill educated.
Ignorant behaviour which harms children is far from exclusive to Africa of of course. Idaho, Oregon and other American states have considerable problems with religious exemptions allowing parents to medically neglect their children health problems, result child mortality 26 times the national average for faith health families. Here the ignorance is wilful, more than it is consequential to poverty and lack of opportunities for learning. And of then there is the anti vaccine hysteria and the measles epidemic.
