if you are a palestinian today then you may have some genetic drift from the surrounding areas, but you are actually a descendant of the ancient jews, who were converted first to christianity by the romans and then to islam by the arabs.
the jews are not your cousins, or even your brothers, but your actual selves.
and, so this is the truth we must come to: some hebrews are jewish, and some hebrews are muslim, but they are all hebrews - and should live together under a pluralistic hebrew state, with equal rights for all.
