Sorry, but you distort history once again. It's true that Romans called Judea Palestine after Bar Kochva's unsuccessful revolt, but it did not mean that there were any Philistines left. They have integrated a long time ago into the native population. It's even wronger to claim that Jews formed the majority of the population after Bar Kochva's revolt. They were only small pockets of Jews left in Palestine, mostly in the Galil. The majority of the inhabitants were Arabs and a mixture of original Canaanites and Arabs. They did not call themselves Palestinians, because they had no national consciousness at that time, but they were the people of Palestine. In 1948, just before the War of Independence (or Naqba from the Arab point of view) there were twice as many Arabs in Palestine than Jews. It is totally irrelevant whether they called themselves Palestinians then, but they do now. The Jordanians did not call themselves Jordanians either, and the Jews surely were Jews int Palestine.
