The reason the current people in Greece can show such disrespect for ancient Greeks (Black and White), is because for the most part, they are NOT related to either.

There was an influx of large numbers of Slavs during the late 6th–8th centuries as well as the migration across Greece of nomadic pastoral groups such as the Vlachs from the 10th or 11th century, and the Albanians from the 13th century, not to mention, the ever present Turks.

So it is that as in Egypt, you get all of these shit-faced people hawkingtrinkets and talking trash, when in reality they are all only squatters.
