Ethnonationalism is a modern delusion. Human beings have been migrating and intermixing since the dawn of our species, even during the Paleolithic. You and I are the result of Prehistoric Egyptians and Sudanese intermixing to form Bronze-Age Nubians who then migrated into the Horn and mixed a bit with local Hunter-Gatherers and then later received some doses of South Arabian admixture.
The English are the result of Celtic tribes overrunning Anatolian Neolithic Farmers and some European HG holdouts only to eventually be conquered and overrun by the Angles, Saxons and Jutes themselves, only for that group to also be conquered and influenced by the Normans to some extent as well.
To say nothing of the fact of the deeper mixed natures of both ours and the English's deeper genetic components like Ancient North Eurasian being ~30% East-Asian-related or our MENA ancestors
having ANA admixture themselves. Don't get me wrong, though.
I am a patriot. I love the Somali language. I love our dhaqan, our diin, our tariikh and even our looks. But I also love humanity, saaxiib. We are all bin adan, all God's creations.
And if in the future Somalis are not brutalized, marginalized or mistreated in any way in a multi-ethnic Somalia then I wouldn't care at all if in 500 years the average Somali becomes 20% Indian, 15% Filipino, 30% Arab or whatever else. Nothing has changed but phenotype;
they will still be human beings and hopefully Muslims. It is the natural course of history and it would be an honor that our country might someday be so prosperous and safe as to attract people from all over the world and be able to give them opportunities whilst still keeping Somalis themselves comfortable.
Patriotism, saaxiib. Not ethnonationalism. The latter is a mentally ill modern invention and the stuff of genocides. Don't catch the taint.
