To the Palestinians, both the (relatively) moderate and the extreme, the Gaza pullout is just the beginning. The admin is claiming it as the result of their political prowess while the extremists are claiming it as victory and validation from their campaigns of "agression".
The Palestinians won't be happy till they have EVERYTHING, including the whole of Jerusalem as the capital of their country which (surprise surprise) Israel is very reluctant to give. If you think the Gaza pullout will solve most problems very soon, that's highly unlikely.
Actually with the extremists gaining popularity because of their "victory" things might actually get ugly when you have people thinking that violence brought around progress.
Plus, if you're saying non-military random targeting civ-terrorists is relatively ok, don't be too disappointed if the extremist Israelis start pulling the same **** on the Palestinians or their own Israeli government. Will people say it's the fault of the Palestinians for stirring up the extremist Israelis then? Probably not.
