Obviously you know little about history. If you draw a line between Venice and Rome, everything bellow the line was Greek. Above the line was Germanic.
That makes Greeks and Italians UNA FATSA UNA RATSA.
After 1000, 80% of Greece was control by either Venice or Genoa.
Some, 60% of all Greeks today are of unknown heritage (ex war trophies sold as slaves). 20% have Italian Ancestry. 5% Albanian Ancestry; the rest are ex Byzantines.
There is NO Greek today without Italian blood and NO Italian with out Greek Blood.
You should be proud of your heritage.
