The indigenous Palestinians are a people who are being denied their land, freedom, and self determination by the Israelis here and now. This is a contemporary problem unlike treatment of the Jews by the Romans millennia ago.
This sets up an unavoidable problem for the anti-Israel team.
Either indigenous and prior peoples have rights or they do not. If they DO, then the Jewish people also have those rights. If they do NOT, then the Palestinians have no rights as a prior people.
You can't have it both ways. Either the people who were there prior to an invasion have the right to restoration or they do not. This cartoon seems to argue that they do not. If child #2 is bumped for child #3, child #3 now holds the rights, yes? That is the implication of the cartoon. Is that what you want to go with?
The slogan "indigenous Pal'istanians" really means Egyptian, Syrian and Lebanese squatters, right?
