Palestinian Jews are native to that area. No living non-Palestinian Jew had ever lived in Palestine or had immediate family living there before European colonization. This is an empirical fact. Your rejection of this fact isn't born from observing material reality, it's a pretext that you think must follow from your unstated premise that forcing living people out of their homes, murdering them, and then moving new people that have lived their entire lives elsewhere into those homes must be morally justifiable. You want to morally justify this because this activity is the basis of your society, and you don't want to feel guilty about reaping the spoils of a society that does that to other people. The way you support doing that to other people while continuing to believe you're a good person is by pretending that the dispossessed are somehow less human or brought it on themselves; that the settlers are actually entitled to the land by god, "natural law", "manifest destiny", or some other flimsy fictional pretext.

There is no basis for conversation, because you're a white supremacist. That you don't want to identify as such is immaterial. Segregationists would similarly maintain that they're not racist and that "it's not a race thing". They maintain that they merely uphold "the natural order". You're firmly committed to the premise that people that seem like you are more human, people that seem less like you are less human, and that it's therefore morally right to kill them and replace them with people that seem more like you. You're unwilling to waver from that premise while it continues to materially benefit you, and so you're unwilling to be convinced of anything that challenges that premise.
