However created this thread doesn't know nothing about anthropology and general phenotypes of Italy.
Italy is not at all gracile med and med only, but mostly alpine and dinaric\dinaricized meds with a fair amount of Atlanto-Meds as well especially in Ligury, Tuscany, Lombardia and Emilia Romagna, but you can find them all over Italy more or less. The gracile meds and berids are to be found mostly in Sardinia, the rest of Italy lacks them mostly save some parts of Calabria. All the pictures of dark guys posted by the owner of the thread are of S.Italian origins, no one of them is from Central or N.Italy. The differences are not enormous but there are and you can notice it.
Livi and Biasutti shown that blonde hair and blue eyes are not rare at all and not only present in N.East Italy or around Alps but scattered in the whole Italy with several enclaves where the % in some cases is striking.
italy is in the centre of mediterranean europe, therefore it received inputs from many part of southern europe, a great part of it belongs to the east med basin type, expecially in southern italy where in the past were greek colonies, the etruscans in tuscany that came from anatolia and arrived there from the crescent valley (tigri/eufate) i think.
the arab influence is scarce and restricted to some place of sicily.
It is not so sure, most of the genetic studies over Etruscans were just biased in favour of Turkye; those same "Anatolian haplos" found "only" in Turks and the people of "Murlo" are presents all over Europe. Furthermore the Etruscans intermingled with pre-etruscan people too; Ligures, Umbrians and Villanovians mostly and any study suggest a mass migration from Anatolia in that time. So the west asian haplogroups found in Italy are mostly neolitich, not from recent historical movements.
about the dinarics you are right, they appearence (that of classical dinarics) is similar to mediterraneans or southern european phenotypes, expecially the dinarid forms toghether with mediterranean the eastern med type.
The dinaric typology doesn't form the eastern med type at all, and it is not similar to med.
The several dinaric types are found in Germany too in large number.
The dinaric type is a central\north balkan peculiarity, i fail to see those countries pure "eastern meds".
As for all the maps posted by some people here, the closeness of Spaniards to French is because of the lack of other Spaniards, as iinstead happens with Tuscans and N.Italians who of course cluster closer being of a more similar stock compared to French.
Italy has had a greater neolitich impact than Iberia, and then it appears a little more "toward" east. In comparison Italy has much less recent admixture from historical periods compared to Iberia, save maybe Sicily.
