Agreed that he doesn´t look Italian its like you say there is Greeks who look very much like Italians/Sicilians and
others who do not.
And it is with some Greeks that they simply have sort of a distinct Greek phenotype which neither truly looks Italian nor
like their Balkan neighbours(Albanians,Slavs)
I have tried to explain these things very often back then in TA but alot of people there like our particular friend wouldn't understand it.
He has always been a completely dishonest broker; nothing he says is to be accepted at face value.
When you're really familiar with certain phenotypes you know the differences which can exist even in one country. That's especially true for a country like Italy where there is so much variation, and I'm sure to your eyes the same might be true in Greece. There are northern Italians who might be taken for people from the Austrian Tyrol or from eastern France or Spain, and Southern Italians who might be taken for Greeks, mainland and especially, perhaps, Island Greeks, and there are Italians who couldn't be anything but Italian.
My father and his siblings, to their constant irritation, were never assumed to be Italian by the Americans here, and even I, who look a bit like my mother, puzzled and puzzle people. I usually get French.
Way back when I was on the 23andme forum and hadn't yet put him on permanent ignore, and having these discussions with him, he wouldn't accept it. Instead, he would post tanned Italians at the end of summer and claim they looked Palestinian.
I'm sure he's still doing the same thing, but he also suddenly started talking about blonde Northern Italians as if he'd known it all along.
Most of the things he spouts which are actually true he just lifted from my comments to him.
Don't take him seriously; in fact, better not to engage people like that at all. You know what they say: never feed the t-rolls.
