First off: nobody is shouting "from the mountains to the sea". That's not a thing. You mean "from the river to the sea" --- the Jordan River being a claimed historical western border of Palestine and of "Greater Israel".

Second off: it is manifestly not the case that everyone shouting that slogan is genocidal. One indication of that: Israel has used the slogan itself. Most people who use it probably don't really even know what it means, as seems to have been the case there.

Third: please stop declaiming. It's not persuasive, it doesn't teach anybody anything, and it pumps cortisol into the thread. You don't have to have a thing to say here. Sometimes it's best just to let charged threads like these die down on their own.
