The issue is those people who want to completely dismantle the state of Israel and evict (or kill) all the Jewish inhabitants. They call themselves "anti-Zionists", but they are simply racists because they are fine with the Arab citizens of Israel.
This is equally as wrong as those Israelis who want to wipe Gaza off the map and occupy the entire West Bank. Sadly for the Palestinians, a bunch of people who believe this are part of the Israeli government.

And entirely different matter is the fate of the people who are not citizens of the state of Israel. Where do you hope for them to live (and why)? Surely not in the pluralistic state we just talked about, since peaceful coexistence is far from a mainstream viewpoint among that population, to put it mildly.
A relevant Ask Project video from recent memory: https://www.youtube.com/watch?v=Grq1Ro9vlyU - note that none of the Palestinians consent to living peacefully with the Jews in one state.
