Palestinians are ethnic Jordanians.
Yes.
And most Jordanians are “Palestinian” Arabs ...
and:
Arabs are Arabs are Arabs...
Migrating from one part to another, throughout.
No they aren’t. They’re Arabs of other extraction. Even Zuheir Mohsen, who admitted the nonexistence of “Palestinians”, knew there was a distinction.
Strictly speaking there is no distinction between Jordanians and other Levantine groups.
The “Arabs” in the region from the Sinai to the borders with Turkey and Iran are a mix of Canaanites, converted Israelites, assyrians, sumerians, amorites etc.
The Palestinians do have some Jewish ancestry,
