> Well, if your logic is pretending to be universal, then it should apply to Palestinian Arabs as well.
It applies to the State of Palestine as much as to the State of Israel, correct.
Of course, while I have heard many arguments for recognition of a State of Palestine with twrritory including some parts of the area bounded by the Mediterranean Sea and the internationally recognized borders of Egypr, Jordan, Syria, and Lebanon, none of them have been that that State has a “right to exist".
And I haven't, in this discussion, stated a position on whether either Israel-within-some-borders or Palestine-within some-borders are proper realization of the right of self determination of some people living in the area described above. You’ve just assumed a position out of nowhere because I argued that a “right to exist” if the State of Israel is a fundamentally flawed and problematic position, with a reasoning that on its own terms applies equally to the same argument if it were made for the State of Palestine.
FWIW, I think the best realization of the self-determination rights of the people in the region would probably, in the near term at least, involve both a Jewish and a Palestinian Arab State within some borders, a situation to which there are many obstacles, not least of which is Israel’s long (consisting of most of the time since 1968 at least) campaign of genocide against the Palestinian Arab people, callibrated largely to avoid excessive blowback from the West (and particularly the US), with strategies enggaged in to preserve pretexts for continuing and escalating that campaign with reduced resistance, both direct and dippomatic (which includes, among other things, fostering the formation of Islamist network that gree into Hamas to split Palestinian resistance and have a less sympathetic organized opposition during the occupation of Gaza.)
