Perhaps I should clarify. zionists are non-human demons. Therefore, zionists are incapable of possessing any rights pertaining to humans…including any rights of self-determination. Consequently, when I speak of the UN mistakenly referring to the “state” of the impostors of “Israel” I’m doing so purely as a hypothetical abstraction for the sake of illustrating and discussing the inherent contradiction of this “Israel” touting its own authenticity by citing UN resolution 181…not because I believe the UN or any other body could magically create rights of statehood for non-humans.
More directly to your point. Your example “fallacy” it itself flawed because the decision of some states to recognize another…or not…has no bearing on whether that state actually exists. If a person jumps off a roof of a building then insists repeatedly that the ground does not exist, their self-delusion will ultimately harm only themselves. Reality is not dictated by individual belief nor by collective consensus. If everyone in a group believes a lie…it is still a lie. If no one believes something that is true…it still remains true.
