How come nobody talks about all the Israeli-Arabs who want no part of a Palestinian state?

Many Arabs insist that a two-state solution must not include transferring Israeli-Arab neighborhoods to Palestinian control. Arabs claim it would hurt their businesses and be bad for the economy.

So let me get this straight. Any future Palestinian state would have to be Judenfrei (Jew free). But Israel must allow Arabs to continue living in Israel? Israel was stupid not to expel ALL the Arabs from Israel in 1948 in exchange for all the Jews who were quickly expelled from all the Arab states (forced to leave all their property behind)
