I have heard that there were few people, and that many of those people who were there were Jews living in effective slavery under Islam.
I have also heard that the people who lived there under the Ottoman Turks welcomed the change when Britain took over during the first world war.
I have heard that the Muslims had become upset that the Brits tried to restrict the more violent aspects of Sharia Law that in the 1930s the Muslim population aligned itself with the NAZIs and that the Palestinian Mufti himself spent the war in Berlin collaborating with the Germans. Particularly on matters pertaining to the Jews.
I have heard that when it appeared that Jews (fleeing extermination flooded into Jerusalem and the land of ancient Israel in the late forties appeared likely to be granted their own state by the government against whom the Muslim populace had rebelled during the second world war) were possibly going to be granted their own state a great ragtag jihadi multitude of rabble flooded into the area from all over the Muslim world. A population that vastly exceeded the native Muslim numbers.
In short, I have heard that most Palestinians are not, in fact, descendants of people who lived in the area for centuries. They are descendants of a jihadi army who came to kill Jews.
Don't lecture people on history Jack Sara. You don't seem to know much of it.
Instead, tell people of God's plan to remove the punishment for their sins by taking that burden on himself and dying in their place. If you really are an evangelical.
