For me it depends, if the kids know af somali and Dhaqan. I wont see them as full somalis biologically, but as half somalis who embraced their mothers or fathers heritage.
I am not in favour of mixing for obvious reasons, but I would never hate on the kids or their parent.
Please no gaalo, if they want to marry outsiders then muslims should be the only option. Cant imagine having half somali kids running around with gaalo dhaqan, worshipping other gods and eating pig.
Couldn't have said it better
