I can literally name ladies in their 50's and 60's that are/were married to cadaan men off the top of my head. Admittedly, the majority got married after 91. They're gen 1 nevertheless.
And to say intermarriage didn't happen in Somalia is just being dishonest. If I recall correctly there were 300k Italians in Muqdisho in the mid 60's. At that point they were already rooted and had families present. There was just no need for them to mix in large numbers. Somalis were relatively opposed, but if an Italian insisted on finding a Somali woman, they would. And they wouldn't be prostitutes either. It's just a mixture of factors that killed any incentive.
I lived and spent years in one of the largest Somali hubs in the West. I assure you, I am Somali lol
P.s. you're not going to like this, but marrying out,
especially as men is not cooning
