1) Using your logic, why would a Turk share the same heritage and identity as someone from Vienna?
2) Surely a Sicilian has as much (if not more) in common with a Libyan as he does with a Swede.

I'm sure you do (just as they share it with others, no man lives in a continental vacuum), but when was the last time you read Camoens?
