Great then! I'm glad to be wrong about that.
You are much more educated about Mathematics than I.
Please correct me about this.
But I think your meaning is that this is all irrelevant drivel that is as a matter of course ignored by any Mathematician, and that it doesn't count for anything that would even get mathematics wet by a single drop of spittle.
The problem is that it is not Mathematics. It may be a philosophy of some sort, and it may provide a basis for mathematical development, but it is not Mathematics.
The barber's paradox is simply a self-contradictory statement. The statement, "The barber [a man in the town] shaves every man in the town who doesn't shave himself", appears to have meaning, but doesn't. A less decorated version is "This statement is false". In this form, it's lack of meaning is more apparent.
The loose rules of English let us form self-contradictory statements and give them apparent meaning. However, Mathematics works from well-defined rules that make such statements impossible.
The Bertrand Russell Paradox was significant because it pointed out a flaw in the set theory of the time. Set theory did allow self-contradictory statements. That was a huge problem for Mathematics because set theory stood at the base of Mathematics, and that was a very bad place to find a contradiction.
Russell's paradox has been resolved, and Mathematics' integrity is restored. ZF Set Theory was one approach; it simply prevents self-reference. Mathematics can accommodate many approaches, so there are others. Hierarchical classes is another approach and possibly inline with what you are attributing to Doron.
At any rate, Mathematics isn't constrained to any particular model or philosophical point of view. Doronshadmi's distaste for absolute infinity doesn't in any way forbid Mathematics from having an absolute infinity, or several of them, and they can coexist in harmony with potential infinity.
Philosophic insight may provide a basis for the development of some mathematical system. The glimmer of insight Doronshadmi occasionally exhibits among his contradictions, misunderstandings, and meaningless vocabulary provide the occasional example. Mathematics has room for many such things, even those that contradict others. However, Philosophy does not constrain Mathematics.
