The converts they make in developing countries are often very unlike the jws from the mother countries, they are on a complete different level of indoctrination than we were. It is true that demonism and superstition still play a huge part in many of these ones lives, even after years of being in the org. The way in which many live their lives in African countries for example; is very similar to when the first christian missionaries of christendom arrived. They just accept the witness deal and carry on believing all the superstition underneath.
I have seen african brothers having their naming parties, putting the thread around the childs hand, bible under pillow etc. Many believe in curses etc. The org claims to be successful in removing these traits from the new converts but that is a lie, scratch the surface and it is still there.
The interesting part will be when the level of information reaching such ones is improved. Africa is leapfrogging with regards to technology so in the future the internet over mobiles etc will play its part. But the interesting point is that many of the new converts are just religious people very much like the majority in their country. In Nigeria there is a church on almost every street corner, preaching is accepted by many denominations and the name Jehovah is not exclusive to Jws.
