I suspect Quine's statements were much more nuanced than your
understanding (or misunderstanding) of them would suggest.  Since you
can't cite Quine's original text to back up your assertions, it seems
more likely that these assertions are falsehoods.

Two Dogmas of Empiricism --- Willard Van Orman Quine (1951)

I am not going to wade through his double talk and weasel
words any more deeply that his issue with how the term Bachelor(x)
gets its meaning. He totally screwed that up proving that
he is clueless about how words get their meaning.

Or, far more likely, you are clueless about what he actually wrote, and
what it means.

You can just keyword search the term 98 instances of the
term [synonym] and see all of his mistakes.

I could, but I'm not going to.  I put it to you, again, you have not read
and understood that paper of Quine's.  It says things you don't like,
that you can't counter logically, so you just end up cursing.

You haven't provided any evidence for you actually having read the
original.  You're likely just quoting somebody else's opinion of that
original.

If anyone in the universe says that the analytic/synthetic
does not exist we can ignore everything that they say and
provide the details of how analytic truth works:

*Semantic logical entailment from a finite list of basic facts*

In other words, if anybody disagrees with you, you bad mouth them.

Not on this. This material is difficult.

I don't doubt it.  So why don't you conclude that you might not have
understood it fully?

[ .... ]

The entire body of human knowledge that can be expressed in language
is an axiomatic system beginning with a finite list of basic facts.

You've never proven that, and it is almost certainly false.

A valid counter-example is categorically impossible.

OK, take the true statement "Nuremberg is a good place to live.", a
statement expressed in language.  Please state the axioms from which this
can be derived, and show that derivation.

I don't think that value judgments can be derived
from basic facts thus do not count as knowledge that
can be expressed using language.

OK, so you remove from "the entire body of human knowledge that can be
expressed in language" everything that _can't_ be derived from your
axioms.  That's circular and tautological.

Even if you did this, what you would end up with would be an impoverished
lifeless mechanical subset of knowledge.  You would have no music or
arts, no reason to get out of bed, even, no experience, and no human
relationships.  Amongst other things.

All these things can be expressed in language.  They cannot be derived
from some set of axioms.

Keep trying to come up with counter-examples so that
I can generalize to prove that counter-examples are
categorically impossible.

If you keep changing the rules every time I give you such a counter
example, then clearly I can't.

As I said, it's up to you to prove your assertion that the entire body of
human knowledge can be derived from "basic facts".  You haven't yet given
even a single example of such a basic fact, never mind some derivation of
useful human knowledge from it.

I doubt very much you can do this.

  From this list the rest of general knowledge that can be expressed
in language is derived through semantic logical entailment.

Apart from the bits which can't be.

Such bits are categorically impossible for the entire
body of knowledge that can be expressed in language.

Wrong.  I just gave an example above.  I think it likely that most bits
of knowledge expressible as language will not be derivable from your
axioms, of which you have yet to give a single example.

Try again. Value judgements do not count as knowledge
because they are not semantically entailed from basic facts.

You're simply wrong, there.  Knowledge is very much build up from value
judgments.  There are no such "basic facts", apart from in specialised
fields such as mathematics.  The universe is simply too rich, too
colourful, too multifacetted to be reducible to some sterile system of
"basic facts".

The burden of proof is on you.

As yet, you have not met that burden.
