@Geri So the meaning of that phrase is this: "a phrase that can be used to call for the elimination of the State of Israel and/or ethnic cleansing of Jews living there, to be replaced with Palestinian control over the entire territory from the Jordan River to the Mediterranean Sea"

It is antisemitic in nature (originally) and the woman either intends a genocide of Jews in Israel (Hamas) or she is supporting the genocide of Palestinians in Gaza. (Israel) Either way it is hate speech.
