The 1.3 billion muslims you refer to are not going to be faced with a potential choice of citizenship - muslims in Indonesia, Saudi Arabia etc have nothing to do with Palestinian citizenship. You are just bitter that the poll revealed something which you don't like but has long been known in Israel - Israeli Arabs and Palestinians would prefer to live in Israel than under Palestinian rule. And to further your point you try to degrade the intelligence of those polled "I bet the majority of those polled are laborers,car mechanics" - even if that were the case, are laborers and car mechanics not free to have an opinion? Not free to have hopes and dreams?
