In this conflict the narrative defines your position. A Jewish person might say those people occupied my historical homeland to which they have no right to and from which I've been forcefully removed. A Palestinian can say the Jewish people displaced my ancestors from my home by force. They're both right (to some degree) and both positions are not useful to actually getting a peaceful resolution, they are typically used to justify non-peaceful actions. There's also a lot more detail/colour to those statements and history than meets the eye, some agreed to facts and a lot of historical debates.

I would also add to that that IMO the specific criticism of Jewish people borders on antisemitism. There are very few people on this planet who live on land that was not taken by force from someone at some point, sometimes in very recent history (is there a statue of limitation on this stuff?). There are also many people who immigrated in recent history from one place to another. At the same time there's certainly much to be critical of. I would also say the characterization above of "turned into colonies" is factually wrong. Even if we look at it solely from the Palestinian narrative I think you want to tread pretty carefully, especially if you want someone to listen to your position/argument and maybe change their minds.

All that said, we have to move forward (both in Israel and the rest of the world) through some sort of reconciliation that can acknowledge the wrongs and make amends while at the same time realizing we can't turn the clock backwards. Clearly (to me) there are win-win solutions that are much preferable to the ongoing conflict.

EDIT: I find this story very inspirational and something that hopefully can show everyone that despite all the challenges it is possible to move forward to a better place.
