Where did you get the stat that only 90% of us are born muslim? If 10% of somalis where born gaalo we would personally know gaal somalis.What makes it even worse is that a Somali kafir is most likely a murtad. With 90% of somalis being born Muslim most Somali kafirs would have been born Muslim and them left Islam.
This makes them even worse then a Kaffir who is born Christian or Jewish. As being an apostate is much worse in the deen then being a disbeliever as you were born with the xaqq and then left it out of choice.
I personally have no love or connection with any murtad Gaal Somali. A Chinese Muslim and I share more brotherhood and love then a murtad Gaal Somali.
I would much rather welcome a Chinese or Indian Muslim into Somalia and kick out that Gaal murtad Somali , as the Gaal murtad will spread his Gaalnimo and the Muslim ajnabi will live in peace and harmony.
Somalia is not only an ethnostate but it also has 1 religion. There is many people who were Somalis and were excommunicated for their Gaalnimo like the rendille and other tribes.
