"Of course the state of Israel has no right to exist."

I don't agree with this. Whatever you think of what happened seventy years ago, Israel is not just a slab of land. It's the home of eight million souls, most of whom were born there, who couldn't help being born there. Yes the Israeli regime is a monster. Land is stolen for illegal settlements, a determined effort is being made by the regime to undermine any chance of a two-state solution, Palestinians are discriminated against and Gaza has been turned into a besieged hellhole. All these things are supported unconditionally by the US with the connivance of other western countries. That's what is wrong and we should fearlessly address these things, but we can do that without wrongheadedly denying the right of Israel to exist. There's no going back on that basic point any more.
