You're mixing two completely different things here.
Arab-Israelis (meaning Israeli citizens who are Arabs, which represents about 20% of the Israeli population) are not "exiled" to the WB, they don't live in the WB, they live in Israel, and are full citizens - no one can exile them anywhere.
There is some discrimination, sure, but in almost every respect they are equal citizens of Israel.
