You can't understand not wanting to leave but instead voting via democratic process only to be dissatisfied/alarmed that more authoritarian, right wing demagogues are pushing the Overton Window right and eroding democracy?

Do you live on Mars? This is happening everywhere.

I'm sorry if this is a stupid question, but if half of them want peace and are secular, why don't they just leave and go live somewhere else?

To quote some "very fine people" from a major western nation. "Jews will not replace us".

Lots of places aren't exactly welcoming to them.

Jews living in other communities has been tried and generally found not to work; it might be OK for a while but eventually they get scapegoated, persecuted, and in one extreme case sent to not exactly a holiday camp in Auschwitz. So they need a land of their own. Where though is the question, because there isn't much usable land on this planet that hasn't been claimed by someone, so those people are going to be displaced, some more willingly than others. Personally I think since the USA are their biggest fans they should get one of those 50 states to themselves, and it'd be a lot cheaper to just buy out everyone in the state than to keep trying to keep Israel safe from all the enemies that currently surround them, but what do I know.
