Somali culture is intertwined with the religion of the Somalis, even our folklore songs are embedded with prayers upon the Prophet, and praises for Allah, the ex-Somali community if public have no chance of having a presence in the motherland, the children would stone them, the youth will abuse them and the adults will crucify them, they are outcasts and I can tell you that somalinimo goes when you leave the deen.
The only place for the ex-Muslim is the west, and power and dominance in the world is not exclusive to a civilisation, it may be in our lifetime that the west as you know it will come to ruin, indeed power and world dominance are inexclusive, and the trend of excommunication is nothing but a product of western civilisation.
