I have been here decades, a lot of it was from the Christian Church and their missionaries going into the Bush to civilize the "Natives".  Nothing like a group of any kind to show up in your remote village, hand out "goodies" and bibles and tell you that everything in your culture is wrong and immoral. I have been told that by a lot of people in those communities and they hold a lot of resentment for the intrusion in their lives.
