You keep saying Helen Thomas said the Jews "should get the hell out of Gaza."
She didn't say that. She said they should "should get the hell out of Palestine."
When Helen tals about Palestine, she is not talking about an independent country of Palestine (that has yet to exist) or about the Palestinian territories of Gaza and the West Bank; she is talking about Israel proper. Those that do not accept that Israel should be its own country refer to the whole area as Palestine. Look at any map published by Hamas or even the PLO.
When she says go back to Germany and Poland, this is a direct reference to the Holocaust.
BTW, the majority of the Jews now living in Israel are (or are descendents of) Jews who have been expelled from Arab and Muslim countries in the Middle East. For the most part, these are the Israelis taking the hardest lines.
