To Answer your question you'll have first to define which Israel do you see as the land of the Jewish People.
1- Is it the Israel defined by International Legitimacy (UN Resolutions)?
2- Is it the Defacto Israel occupying Palestininian, Lebanese and Syrian lands?
3- Or is it the Biblical Israel from the Nile to the Euphrates?
I think if you can pick one of the choices above you'll automatically have an Answer to your question.
As an Arab I have no problem with the first option. Neither do the other Arab nations, in fact an Arab peace Initiative was presented in 2002 supporting this scenario.
As for the second option, where Israel is deliberately occupying the lands of others and claiming it as its' own, in defiance of the entire world community. Of course it is wrong, and critisizing Israel becasue of that is not only legitimate but is a duty on every human being who loves justice and peace.
As for the third option its a pure fantasy, but regretably is still spoken of among many extremist Israelis who claim rights in the lands of all their neighbours. This is obviously insanity on an unprescedented scale. It only contributes in inflamming emotions, and adds to the hatred floating in the air.
I would equally add that current Israeli policies are not helping them better their immage either. Maintaining Military occupation through appartheid like laws, Blockades, forced evacuations, illegal settlements, assassinations, Home demolitions, farms destruction, targetting civilians, collective punishment etc... etc.. who in his right mind will support such actions.
The Israeli talk about historical rights dating back from the "Bronze age" is as absurd as denying the existance of the Palestininas. But they just do it any way since hidding the truth is easier when you flood the discussion with irrelevant speech. As I said before in many posts it's just part of their "Fogging" tactics. I wouldn't go down this road any more it has been discussed exhaustively, and is frankly useless.
Facts remain simple and srtaight forward I can sum it all up in the comming few lines.
Israelis and Palestinians exist and are there to stay.
Israel occupies Arab lands (West Bank, Gaza, East Jerusalem, Golan Heights and Shebaa farms)
Arabs have rights that Israel must recognize in accordance with the will of the international community.
Arabs have presented a peace initiative in 2002, calling for a just and comprehensive peace with Israel based on UN resolutions 242 and 338. Calling for the withdrawal of Israel from the above mentioned Arab lands in exchange for peace, recognition and Normalization (Israel has refused it so far).
Any specualtive talk going along the lines of "if the Arabs" will hold their part of the Bargain, or "Israel needs to keep some territory for strategic security issues, or "peace initiatives aiming to annhilate Israel" is simply hogwash, and falls under the "fogging" Category. Arabs have demonstrated in the past that they are willing to maintain their part of the deal if Israel is willing to recognize their rights (you have the example of Egypt and Jordan)
Israel chose to be an occupying and oppressing power, and must accept the consequences of its choices. Critisizing its policies being the least any conscient human being can do. But how could the "chosen people of God" accept any critisizm! aren't they supposed to be a perfect superior race! So they have mastered a few techniques to silence and persecute any legitimate opposition by victimizing themselve and aiming their ultimate weapon, the accusation of "Anti-semitism" against all opposition. Or calling regular critisizm "Picking on" as you just did.
Sorry for the long Answer
