In the jungles of the Amazon, there is a very strong custom of burying children alive for various superstitious reasons. The practice goes on even now and has been covered up by the Brazilian government, as well as various Indian rights organizations, who are trying to stop outsiders from violating "native rights" by attempting to stop this barbaric practice.
The video clip below is from a documentary that shows a real tribe carrying out this ceremony - putting two children in a pit to be buried alive. I believe one escapes, but as far as I can tell the first child dies.
This is horrible and needs to be stopped - this is an example of why we need solid missionary preaching and repentance and conversion among these people, not a simple dialogue. This is a demonic, wicked thing these people are doing, and equally wicked are the "activists" who try to preserve the custom in favor of native's rights. These activists would defend Aztec human sacrifice if it were still around.
Missionaries, get down there! Preach Christ! The Evil One delights in the slaughter of innocents and has since the beginning...Preach Jesus and stop this abomination!
