The other side is when the Jews were thrown out of the Muslim countries and their property stolen. Not in a civil war, but just from racism -- because they had the same religion as in some other country.
Note here that more Jews fled from the Muslim world than Palestinians in the Nakba. And in the fleeing Jews' stolen property there were more land than multiple times the size of Israel.
Contrast this with that not every Palestinian fled from Israel. They are still a large part of the population today -- the Israeli Palestinians were NOT thrown out as a reaction to when the Muslims threw out their Jews.
And you are really, really upset about Israel -- but dismiss the worse things happening in e.g. your home country Tunisia...
I have to stop here -- any further comment on your opinions, moral and intellectual integrity can't be polite. Let me just say that as a Westerner, I think you should judge yourself harder than you judge others.
