So you are going to be stupid? thats how its gonna be?
Italians who are of mostly Etruscan heritage are now mixed, while the italians that were raped by the Cimbri, Celts, Goth, Huns and who knows what else, they are absolutely 100% pure italians.
This is how the Etruscan painted themselves
Italy is also one of the European countries with less admixture because of how isolated they are by sea and mountains from everyone else, and because they were good warriors so they managed to keep people out.
