Do you think that African Witch Doctors are more likely to be swayed by Witch-persecutions or by Christianity?

I want Christian answers only,I am not interested in Magic.Does when an average African Witch Doctor be swayed by the tradition of Intolerance in Europe?Or do they lack power in Europe because of the Christian Faith?I have been cursed recently and I really thought they weren't rediculous now I'm not so sure.
