Check the statistics I linked though and you’ll find that 50% of Palestinians don’t want peace as long as israel exist.
Moreover, half (50%) agreed with the following proposal: “Hamas should stop calling for Israel’s destruction, and instead accept a permanent two-state solution based on the 1967 borders.”
The question is two-pronged, asking both whether Hamas should change their demands and then narrowing the possible solution down to one specific peace alternative that we know many Palestinians would be deeply unhappy with, given that it would mean substantial territorial concessions and might well also have been interpreted as largely giving up the very thorny right of return demand.
Nothing in this question asks people to agree or disagree to "peace as long as Israel exist".
A more reasonable interpretation is that half of Gazans are support substantial concessions before even starting any negotiations by expressing support for a kind of peace that'd involve the Palestinian side giving up on big territorial claims from the outset.
