"It's more because of the incidents when the Israelis do things like use WP deliberately on civilians, shell families on beaches, use Palestinian civilians as human shields for the IDF and the countless incidents of deliberately shooting unarmed civilians - especially children, to name just a few very well documented incidents of the thousands that are contentious..."
Are you sure you've got your facts straight? Are you the same person who thought the (not Jewish) "Palestinians" were on the allied side in WWII? I haven't seen any links/evidence of what you're claiming.
"But also by the indigenous population that were illegally expelled by a terrorist campaign against their villages and then forced on a "death march" and those that survived were not allowed to return, were not compensated for their seized lands and property and have been victims of a subsequent genocide campaign."
Again, you are confused.
The Exodus of 1947-48
The Palestinians left their homes in 1947-48 for a variety of reasons. Thousands of wealthy Arabs left in anticipation of a war, thousands more responded to Arab leaders' calls to get out of the way of the advancing armies, a handful were expelled, but most simply fled to avoid being caught in the cross fire of a battle. Had the Arabs accepted the 1947 UN resolution, not a single Palestinian would have become a refugee and an independent Arab state would now exist beside Israel.
The beginning of the Arab exodus can be traced to the weeks immediately following the announcement of the UN partition resolution. The first to leave were roughly 30,000 wealthy Arabs who anticipated the upcoming war and fled to neighboring Arab countries to await its end. Less affluent Arabs from the mixed cities of Palestine moved to all-Arab towns to stay with relatives or friends.
All of those who left fully anticipated being able to return to their homes after an early Arab victory, as Palestinian nationalist Aref el-Aref explained in his history of the 1948 war:
The Arabs thought they would win in less than the twinkling of an eye and that it would take no more than a day or two from the time the Arab armies crossed the border until all the colonies were conquered and the enemy would throw down his arms and cast himself on their mercy.
By the end of January1948, the exodus was so alarming the Palestine Arab Higher Committee asked neighboring Arab countries to refuse visas to these refugees and to seal the borders against them.
Meanwhile, Jewish leaders urged the Arabs to remain in Palestine and become citizens of Israel. The Assembly of Palestine Jewry issued this appeal on October 2, 1947:
We will do everything in our power to maintain peace, and establish a cooperation gainful to both [Jews and Arabs]. It is now, here and now, from Jerusalem itself, that a call must go out to the Arab nations to join forces with Jewry and the destined Jewish State and work shoulder to shoulder for our common good, for the peace and progress of sovereign equals.
On November 30, the day after the UN partition vote, the Jewish Agency announced: “The main theme behind the spontaneous celebrations we are witnessing today is our community's desire to seek peace and its determination to achieve fruitful cooperation with the Arabs....“
Israel's Proclamation of Independence, issued May 14, 1948, also invited the Palestinians to remain in their homes and become equal citizens in the new state:
In the midst of wanton aggression, we yet call upon the Arab inhabitants of the State of Israel to preserve the ways of peace and play their part in the development of the State, on the basis of full and equal citizenship and due representation in all its bodies and institutions....We extend our hand in peace and neighborliness to all the neighboring states and their peoples, and invite them to cooperate with the independent Jewish nation for the common good of all.
