Both things can be true at one time, saving from persecution and expanding the Jewish population.
Doesn't US money say "In God we trust"? Don't various Christian countries put up Christmas decorations and trees everywhere? Aren't there courthouses in the US with the "bible" statues in front of them? I think the US is more of a "Christian" state than Israel is a Jewish state.
Israel is primarily founded as democratic free secular society, not a Jewish State in the sense you're implying: "will promote the development of the country for the benefit of all its inhabitants; will be based on the precepts of liberty, justice and peace taught by the Hebrew Prophets; will uphold the full social and political equality of all its citizens, without distinction of race, creed or sex; will guarantee full freedom of conscience, worship, education and culture; will safeguard the sanctity and inviolability of the shrines and Holy Places of all religions; and will dedicate itself to the principles of the Charter of the United Nations."
Anyways, in the sense that Israel is the country of the Jewish nation, like Japan is the country of the Japanese, and China is a country for Chinese, and India is a country for Indians, that's sort of true. But I don't think this is the point you're trying to make here?
I did a quick Google for surveys from the Israel Democracy Institute and I failed to find a survey saying Israelis hate Palestinians. Maybe point me to the specific survey(s) you had in mind?
I don't think Ofer Cassif was being expelled for "defending international law". Israel is abiding by international law. Anyways, if he wasn't that shows you democracy in action. How many senators e.g. in the US were "defending international law" by opposing their country internationally post 9/11 e.g.? Israel has a diversity of opinions (of which Ofer is on some extreme) and the freedom to voice them.
