This totally revolting and shows why we must stand up and fight religion. Fight every superstition, spread skeptic ideas. Not all religious people are like this, fortunately, but the fact of believing that blind faith is good and that inquiry is bad, can easily lead to this monstrosity.
These children are victims of "pastors" who abuse them and live from the naivety and cruelty of their fathers. Worse is that these pastors are not that different from a lot of local (and American) pastors, with their insistence in the reality of demons.
Things like this make me sick, but also painfully aware of the necessity of helping to the coming of a better society, of the utility of educating people and trying to get the youngsters into critical thinking. The West was no better 1000 years ago, but now we know how to change things, we know how education can improve things, we know how technology can help people. Hopefully this won't last much time, if public outrage spreads and Nigeria is pressed into doing something (But they also have oil, so they might be not pressed at all). Please, reader, share this video and make that happen. Let's try to help these poor children, one of them could be a developer of key solutions to some of our current problems in the future. We are at risk now, we cannot allow to waste any more ingenuity, our survival as species is at risk.
