I don't recall i've ever argued against that, if anything I said that Israel should evacuate the Settlements.
And "as is well known" doesn't mean anything, it isn't the most densely populated area on earth, it isn't one of them, it isn't even among the top 200.
I've also never stated that they have nothing to be angry about, it seems like you're arguing mostly against a strawman, i've told you why shooting rockets only harms them.
And i'll ask (again?), if we can't use grossly disproportionate force, how would you like us to stop Hamas firing rockets? No, leaving land won't help, they've already proved so in 2005:

And you can be damn sure that we would do our best for the safety of Israeli civilians, if you think we can do better, while having similar or better rates of success, please tell me.
