So would the same count for Muslims? How many of the muslims in Israel are the desendents of the original Jews who were forced into converting?? Should they live in Israel?
We also don't know how many Christians in Israel really support Israel. I know some "Palestinian" Christian groups who are jsut as anti-israel as the Muslims are.
Judaism and Christianity are both from the same root. Islam, on the other hand, is a rejection of the promises to patriarchs from Abraham to David. Thus, if you are to base tenure in Israel to the promises of the Old Testament, then the Muslims have apostatized and placed themselves outside of those promises. The same cannot be said of the Christians. They represent the fulfillment of those promises.
As for the Christians supporting Israel, what is your definition of that support. To support Israel must the Christians declare that those ethnic Jews who reject Jesus as the Messiah have special rights to the land that ethnic Jews who profess Jesus do not?
