the argument they pass beacause they are "Alpine" is an odd one because it depends on your definiton of it. This kids look more Taurid and Asiatic Alpine, which some similar looks could be found in South Italy (and it would not be dependend on head shape), but Arabid and Nordid too if you want.
You could actually argue that the genetically removed Ainu man can pass in Southeurope with an other outfit. So only small details seperate Caucasoid looking groups on individual level anyway.
