I don't think there is any path to discourse with one of your first principles being that none of us can have an equally valid position as the Israeli government. It is really an amazing position to hold for someone that lives and grew up in a democratic republic.
It's not you can't have a discussion, you're just not making very good points/arguments.
First, and I don't think you're arguing this, there is not a moral equivalence between the Israelis and the palestinian terrorists. The Israelis are taking every conceivable step to prevent civilian deaths while defending their homeland, whereas Hamas is both targeting Israeli civilians
and encouraging its own civilians to die.
Second, as for the "peace process", that is entirely up to the palestinians. It is simple logic that you cannot make peace with a neighbor if you deny that neighbor's right to exist. Once the palestinians clear that hurdle, peace is possible, but not until then, and a majority of palestinians currently favor terrorist government. Thus, those who condemn Israel for not making peace either (1) are ignorant of the foregoing logic, or (2) secretly or not-so-secretly believe that the very existence of Israel
is the problem.
