What about expelling Jews from Palestinian homes?
There are no Israelis in Palestinians homes. There are lands that are in debate to who they belong. that's the difference.
But there is also the knowledge that "two wrongs don't make a right". You cannot say that expelling Jews is fine since Palestinians suffered that before. And you cannot say that killing Palestinian babies is fine because our children gets killed.
There is certain amount of "wrong" you cannot include in your system. that is not justice, but common reason.
Some people don't have that common reason.
