The hills thing is referring to the land Israel stole in that same conflict as the 1967 one: whatever population was polled went from 71% agree with the Palestinian position to 78% agree with The Entity position, because they changed the wording. They understood the underlying motivations of the population: peace at any cost, reasonable sounding compromises.

It's important to not get stuck softening the language though, ie "tone policing". People have a right to be mad and frankly should use slogans that piss people off. Zios should feel uncomfortable. Palestinian Genocide is great to keep saying because it tells the truth on the ground and keeps Zios not in Israel on the defensive genocide denial stance that never looks good. No need to wait around for amnesty international or the UN or whatever because when Zios come to defend, it leaves an opening to introduce whatever horrors you normally couldn't bring up in conversation.
