"Child witches" in Nigeria: Whose responsibility?

This article appeared in my Sunday paper.
I can’t shake it.

I think anyone who pays attention to the state of the world knows that there are major problems going on in African countries, but I had not heard anything about the fact that thousands of Nigerian chldren have been branded as witches by Nigerian based evangelical pastors, tortured and sometimes killed, frequently at a profit for the exorcising pastor.

On doing some web searching today, it looks like the story has just started getting play here in the US within the last week or two, but I found links from the UK going back to Dec 2007

So there are agencies in Nigeria who are attempting to help the affected children and trying to change laws and beliefs in that country. But where are the “parent” evangelical organizations? If a religious group is going to send missionaries to spread their word to “the heathens” don’t they bear significant responsibilty for what their converts do with their message? I have a hard time hearing we lost touch or we had no idea.. physically harming people.

Is the genie really out of the bottle? If American and British evangelicals decided to try to intervene, could they have a real impact?
