That's probably easier said than done if you live in Gaza, which is surrounded mainly either by barbed wire, land mines, machine gun nests etc., or the sea, except for a short border with Egypt, which obviously doesn't want you either. And even if you get out, what then? You're just a stateless refugee, not even someone from a 'proper' country with a consulate in foreign capitals that night be able to help them.
In fact something you don't hear discussed much is the widespread prejudice and discrimination against Palestinians in the Middle East outside Israel - in the other, predominantly Arab and Muslim, countries.
