Well, considering the Mufti, Arafat, Hamas, etc., I think that yes, the fear that the Palestinians want to kill me (not every single one, but the Palestinians as a group) is, I think, not at all unjustified.
Seems rather like a self-evident truth, if you only bother to read, say, the Palestinian charter or the declarations of the Palestinian leadership or the shows on Palestinian television or the textbooks in Palestinian schoolrooms or...
...well, you get the idea.
So I fail to see why my prediction is unreasonable: why would Hamas, strongly supported by the Palestinians as a whole, show any more mercy to the Jews in America than the Mufti, supported by the Palestinians as a whole, did to the Jews in Europe?
P.S.
As for the "it is safer for the Jews to live elsewhere" argument against the existence of Israel -- that is morally equivalent that "it is safer for Blacks to live elsewhere" as an argument for all-white neighborhoods, or "it is safer for her not to complain" as an argument against prosecuting wife-beaters.
