I mean you could qualify it by saying e.g. "it's a
post-19XX settler colonial movement" - that would be some refreshing nuance on what is otherwise glaringly ideological language, mostly parroted by those who don't know much about the history (hence, I suspect, the disregard you received from another commenter here).
But even then the implication of some global cutoff year after which certain actions are officially no longer "ethical" or "advisable" is pretty ridiculous. Our ethical standards shouldn't vary only by what year it is, but rather ideally by the broadest possible context we are able to fathom. Israel is a unique case with indigenous jews returning to their native land after unparalleled delay, except in terms of borders modern-day israel doesn't perfectly map to ancient judea, and the crazy history of british intervention, geopolitical tension, war, expansion, and attempted peace treaties.
