They do exist, I have met many southerners who have nostalgia for the Italians and feel Somalia has a special bond with that Italians or with other countries(e.g.Turkey). In Italy you have even Somali-Italian associations coming together to commemorate that special bond, history and sing italian-Somali songs.
But perhaps the difference is that Southern would never blast it shamelessly out in the open, as some of our ‘British’ oriented Somali’s tend to do.
