A lot of african are becomming murtad. So I for one think the dawah should be percel for every muslim, more so if one lives in a poorer area. The evengelical have targetted this content along with far east because none is responsive to them in the west where relegion is seen as a bankrupt ism. It is very similar to muslim situation. They become murtad because of lack of spirituality thanks to salafist/non human experience and impersonal take on islam. There is no islam without suluk of some sort. Also muslim immigrant are not the best example. They haven't left their village in pakistan, india, bangladesh. Allahualam
