Non-Zionist Jews and Israelis are a thing. They protest and organize against the religious and neo-Zionist nationalists. They have opinions and a variety of political platforms and compete against them democratically. Obviously, there has been Zionist/religious Jewish terrorism against these other Jewish and Israeli factions, just like there has been or still is political violence in most democratic nations.
The Arabs in Gaza, on the other hand, voted Hamas as their representatives. They do not protest against Hamas or their so called "government". They do not show dissent with Hamas. And let's remember that Hamas' charter calls for the elimination of the Israeli state, not for the 1948 partition agreements or any other form of coexistence.
