If I'm Palestinian, I live my life completely according to the rules of Israel (because of the blockade and checkpoints and control of the territory). As a Palestinian, I also cannot vote in Israel and will never be granted the ability to vote in Israel, in order to preserve the ethnic majority of Israel. As a Palestinian I can also have my home taken away from me to make room for Israeli settlers.
