You miss the point of Russell's Paradox. The barber must not shave himself
to *any least* degree, and yet, as a man of the region, is obliged by law
to be shaved - and nobody else is permitted to shave him (the iff). The
paradox arises in the self-reference loop from the whole sentence back to a
part of the sentence. Fuzzy doesn't apply.
