>By that logic there is no floor: any atrocity becomes "perfectly natural" if the grievance is large enough.

This is mostly true, yeah. Do you not believe that humans act like that?

>In your broader argument you're describing a blood debt with no statute of limitations and no mechanism for resolution

Nonsense.

>Skåne (where I live) was Danish. Alsace was German. Most of Europe was Roman. At some point borders exist, people live within them, and the only available direction is forward.

Except Israel does not want Palestine to move forward.

There are approximately zero living people that give a shit about the things you mentioned, there are millions of living Palestinians who do care and suffer at the hands of Israeli state every single day.

How did you intend for this comparison to be even vaguely relevant?

>you've described a permanent state of war with no exit condition except one side's disappearance.

This is deliberately obtuse, Israel has had a plenty of ways to largely exit this conflict. At the very least they could've given all Palestinians Israeli citizenship and equal rights decades ago.

Of course, that's not really compatible with the ideals of the jewish ethnostate. I'm sure the Palestinians wouldn't seriously object though.

>You just said it's perfectly natural to want to exterminate an ethnic group. Read that back.

I'll repeat it if you want me to. We've seen it over and over again in history, it's hardly a new thing.

Considering how the jewish people choose to treat the Palestinians, it is not surprising that Palestinians want to exterminate the jewish people. It is a perfectly predictable reaction, and not some special quirk of the Palestinians.
