That is obviously NOT what she meant. If she answered the question of where they should go with: "Back inside the green line", that would be an understandable statement (though one I personally disagree with). She didn't say that. She basically said that the nation of Israel should pick up and leave - go back to all the nations that murdered us. Plus it showed a complete lack of knowledge - that the majority of Israeli's are Sabra's or of Mizrahi descent. If was a good old fashioned anti-Semitic statement.
