OC:
Although I have not read it myself, it does look interesting and as someone who is very well read in sub-continental African history, I can say that small quote from the book indicates he knows what he's talking about.
You're clearly interested in African history and the impact religion has had on it so when I get back from vacation I'll go through my books and put together a list of recommended reading if you like (we get back tomorrow so I'll have a good list for you by Tuesday).
During the Rhodesian and Mozambique war in the 70's and 80's there was a constant ebb and flow of refugees between Rhodesia (Zimbabwe), Mozambique, Malawi and South Africa. Unfortunately for the refugees they often traded one poor situation for a worse one. South Africa offered the best stability but most often they were not welcome there and when they were, they would find themselves under the heel of apartheid. Since much of the labor in South Africa consisted of migrant workers from Rhodesia, many refugees used this as a cover for escaping to South Africa. A truly sad and hopeless situation for so many.
One of the strangest observations for me growing up in Africa is the odd relationship which exists between those who call themselves Christians and their cultural superstitions and beliefs. It's as if mainstream religion has created a continent of confused religious orphans who can't quite decide which beliefs should take precedence in their culture.
Interestingly, Zionists have enjoyed a large and ever growing following on the sub-continent.
