Unfortunately we have to deal with the reality on the ground and the reality of Jewish people in the UN partition plan. Reparations must be made and expansion must be rolled back (all settlers out of west bank) but at the end of the day any future must involve either A) a state for Jewish people and a state for Palestinian people or B) A completely united state with full equality for all people.
To me Zionism is the belief that the Jewish people have an inherent RIGHT to an ethnic-orientated state in the Levant based on historical (biblical) tradition. There are many ethnic groups in the world without a homeland, and the crimes against humanity against Jews in WW2 did not necessitate such a state there, if it involved displacing others, which it did.
So I'm Anti-Zionist in the sense that I am against religion-based geopolicy, I am against any inherent "greater" reason for a Jewish state. I am a humanist who believes in the right for safety and prosperity for Jewish and Palestenian people. I am not interested in any solutions where either does not grant the other's humanity or right to safety and prosperity. Beyond that they need to AGGRESSIVELY self-police one another. Palestinians need to self-police (and prosecute) the terrorists and Hamas and keep them to justice. The Israelis need to self-police (and prosecute) the west bank settlers, and reform from the bottom up the IDF.
