1) No modern Palestinian group (not even Hamas) is pushing the "kill all Jews" idea, thankfully. The majority seem to want a two state solution with Israel continuing to exist. And again, Israel is occupying territory; why isn't the onus on them to stop doing that?
2) What does it matter if it's religious or not? Call it religious or political or economic, what does that change?
3) And which of the countries my ancestors left ~150 years ago, that I don't have citizenship in, that (in some cases) don't exist any longer, should I return to, exactly? It was wrong for my ancestors to colonize and occupy Canada; we should take steps to undo that harm in the ways we can. I don't think that's the same situation as asking settlers who actively started occupying an area in the West Bank in the last five/ten/fifteen years to move back into Israel.
Let's look at this another way. How do you think this whole mess should be resolved, ideally? I think a two-state solution is really the only way. What would you like to see?
