Typically people will leave an area of conflict for the safety of their families. Look at all of those who have left Syria and Iraq in recent years. It doesn't mater why they left, they still have the right to return to their homes.
Only if they are prepared to stop all belligerence, violence and terrorism and live peacefully with the rest of the country. Failure to agree with this means they don't want to live in peace
How many Palestinians were expelled because they could not, in fact, live peacefully with their neighbors?
Less that 5,000 according to independent historical sources, the rest left freely on the promise of picking over the scraps left when the arab muslim armies mass murdered all the Jews. Guess the arab muslim armies have never been up to the task..........
From the UN Mediator's final report published after his death (Count Folke Bernadotte and French Air Force colonel Serot were assassinated by Jew terrorists):
UNITED NATIONS PROGRESS REPORT OF THE UNITED NATIONS MEDIATOR ON PALESTINE SUBMITTED TO THE SECRETARY-GENERAL FOR TRANSMISSION TO THE MEMBERS OF THE UNITED NATIONS In pursuance of paragraph 2, part II, of resolution 186 (S-2) of the General Assembly of 14 May 1948
"
Arab refugees
14. A new and difficult element has entered into the Palestine problem as a result of
the exodus of more than 300,000 Arabs from their former homes in Palestine. The measures being taken or contemplated to cope with this problem are described in part III of this report. The question of their ultimate resettlement, either in their former abodes or elsewhere, must be faced and solved. I have affirmed elsewhere in this report that the right of the refugees to return to their homes if they so desire must be safeguarded. Nevertheless, whether or not this right is exercised, most of these refugees will require assistance in some degree to re-establish themselves."
