Funny you should ask...
"The Palestinian people does not exist. The creation of a Palestinian state is only a means for continuing our struggle against the state of Israel for our Arab unity. In reality today there is no difference between Jordanians, Palestinians, Syrians and Lebanese. Only for political and tactical reasons do we speak today about the existence of a Palestinian people, since Arab national interests demand that we posit the existence of a distinct 'Palestinian people' to oppose Zionism." --- PLO executive committee member Zahir Muhsein on March 31, 1977
That's my point. They're sure as heck not palestinians, so what are they? A creole mix?
