It ain't too late. Foreign non ethnics in Somalia number just above a million maximum (I'm being generous). Over all we as a people are 9-11 million. What we are talking about are future trends and if we don't do something about it currently. The quicker we fix the country, the quicker we can do something. Anyway Bantus back home are pretty f-king pure, looks like not much "intermarriage" goes on bro.It's too late. Rahanweyn has already accepted half the Bantu population into their clan system. The Bantu have found a back door to become 1.0
Your only solution is mass deportation to their countries of origin.
We are to blame.
Killing each other
Refusing to farm
Bringing Bantus as slaves
"We" prefer to marry a Bantu than Madhibaan
Refusing to build and construct on our own
Intermarriage if we are not going to deport them isn't even that bad. Its better than an ever increasing Pure Bantu population. With intermarriage we'll in the future if spread out/evened out nicely end up with Somalis being 5-10% non Somali genetically in the future. Not anything significant.
Anyway Somalis being ignorant about this issue is the main problem.
