Just because you inferred it rather than outright saying it, does not mean the accusation didn't happen. Which is another tactic commonly used by trolls, so I'm now pretty sure you're just being a dickhead for your own entertainment and don't actually give a shit about this situation. Further proof of this is the classic: "what you said is wrong. I'm not going to tell how its wrong or whT the 'right' version is, just go do more research, lol" and I'm willing to bet I've read more accounts of the history of this conflict from both sides involved and external 3rd parties than you have.

And that's classic colonialist apologism, "well they had kids here so the land belongs to them now." Like should we consider the Russian invasion of Ukraine. There will have been thousands of Russians born in occupied Crimea by now. Does that mean that land belongs to Russia? Is invading a country completely acceptable as long as you hold on to it long enough for someone to have a kid?

But yes, decolonisation does require the removal of the colonising party. If they can't return to their country of origin or their parents/grandparents country of origin, then they will need to legally immigrate/become citizens of Palestine. Its the same thing that's happened in literally every case of decolonisation, leave or integrate into the new free state. It's just given how Israel has treated the Palestinians I can't imagine many Jews would want to be part of Palestine and face those consequences.
