Well I think there are many reasons.  To be seen as a foreigner in your own area is not like in South Africa.  Here, if I was born and bred at a place, let's say Louis Trichardt and I come here, establish myself, even as a Venda person the local people would say look, he is an outsider, he's made it, he's now boasting, he thinks we are stupid, so they will try to sort of create stories that A is now doing that and hence even if perhaps you were never involved in such things, it might happen that perhaps in this area you are in love with somebody's wife.  Now that particular man who is very unhappy, who is very bitter, will organise young people saying that you are a witch, and you find yourself driven out.
