Unequivocally, and as a Palestine liberation supporter: any call to broadly expel the Jews from the lands of historic Palestine is Anti-semitism.
At the same time, I haven't actually heard this slogan at any marches or encampments in my city.
Regardless, the key is to understand that a Jewish safe homeland in the lands of historic Palestine does not necessarily mean a Jewish ethnostate.
The utopian Zionist dream (not the Kahanist dystopia of "really existing" Zionism) is realizable in a free, democratic and equal binational state, with both Aliyah and the Right to Return for Palestinians, following a Truth and Reconciliation process and the payment of Reparations.
