NOT that I support everything the Israeli government has done, and honestly the whole thing is a clusterfuck of epic proportions if we're being honest. But, there's a reason Israel has the area blockaded and controlled in the first place (or as you put it, has a boot on their neck) - Hamas' goal is the eradication of the Jewish state and Jewish life and culture in the region. They hate Jews, pure and simple. At best, any Jews they might allow to stay if they had their way, would live under strict Islamic control like in other parts of the middle east. If I lived in Israel, I could be the most left-wing person you'd meet and I still wouldn't advocate for the suicide of my people, because I'm not insane.
Hamas does not share western leftist's and liberal's sense of justice or fairness. They are a militant Islamist terror organization. "Leaving them alone" and hoping they chill is a fantasy.
Fuck off.
