LOL. Again, Canaan consisted of three nations. This is a bit like saying France doesn't exist because it is all part of Europe. We keep looping back. It's all good, pretending that Canaan suddenly makes it so Israel didn't exist before the Romans conquered it and renamed it Palestinia doesn't change the reality. Palestinia (Palestine) consisted of three nations, none of which want to be called Palestine. The only people who want to be called that left Jordan (Transjordan) when they took over the area they lived in that they called Transjordan, and informed them that there would be no Palestinian territory, they renamed that region "Jordan" (really just took away the separate designation of Transjordan) and gave them seats in the Parliament. Some of the folks didn't want it, so they moved into another area (Gaza) and created a terrorist organization called the PLO... and the rest is history.
This "Palestine" that generated all these "Palestinians" literally includes jews, Jordan and Syria, and at no time was there a separate nation called "Palestine" from which came Palestinians.
I should consider that folks can call themselves what they want to call themselves, my most considered point is that Jews in Israel are equally "Palestinian" as any Arab who left Jordan to live in Gaza (Israel took them in when Jordan would not).
