I never understood why Israel gets to keep some 1.2 million Arabs, while the Gaza strip and the West Bank have to be made Judenrein. While I think that a Jewish person (Israeli or not) would be crazy to want to live in a place that puts them in harms way (e.g. Hebron in the West Bank, or Kfar Darom in Gaza), I fully support their right to choose to.
James Woolsey, formerly a Director of the CIA makes the same point:

Today we cannot envision the 250,000 Jewish settlers who live outside Israel’s pre-1967 borders being permitted to live at all, much less live free and unmolested, in a West-Bank-Gaza Palestinian state. But some 1.2 million Arabs, almost all Muslim, today live in Israel in peace among some 5 million Jews — about double the percentage of Jews now in the West Bank as a share of the Muslim population there. Israel’s Arab citizens worship freely — one hears muezzins calling the faithful to prayer as one walks around Tel Aviv. They vote in free elections for their own representatives in a real legislature, the Knesset. They give every evidence that they prefer being Arab Israelis to living in the chaos and uncertainty of a West Bank after Israeli withdrawal.
A two-state solution can become a reality when the Palestinians are held to the same standards as Israelis — to the requirement that Jewish settlers in a West Bank-Gaza Palestinian state would be treated with the same decency that Israel treats its Arab citizens. Until then, three failures in 13 years should permit us to evaluate the wisdom of further concessions.
