No one is arguing in support of displacing a population. However, it seems like you believe that everyone should just stay where there are, and no population should ever migrate to any place. That's both naive and simply was never the case in the history of human kind. People migrate, for thousands or reasons, and almost no one leaving on a land on this planet have lived there since the beginning of times.
A piece of land isn't yours because you were born there or your grandpa did. There's one Earth in we need to share it. No one can deny the connection of Jews to the land of Israel, in a same way that no one can deny the connection of Palestinians to the same place. The Palestinians Arab don't need to move back to the Arab Pennisula, where they came from, and the Israelis don't need to move back to Poland, Yemen, Russia, Morocco, you name it. "The times they are a-changin'".
