There are a lot less Jews living in Muslim countries after Israel was created than before. 800,000 were expelled and mostly moved to Israel. You don't hear them whining for the right to return.
There isn't a single jew living in Gaza. Why is that?
It is very much about religion. Hamas is an explicitly Islamic supremacist organization that calls for the destruction of Israel as a religious obligation.
What do you mean there isn't a single jew living in Gaza? How is that relevant? That is entirely beside the point.
If you had the option to live as a full citizen in Israel, being told you're part of the dominant ethnicity that's treated as human beings; or staying in Gaza, where you are being bombed to death by the IDF, I wonder which you would choose?
Your argument is essentially stating the conditions of apartheid as negative for dominant ethnic group. I didn't know someone could be so divorced from reality.
