Let us help you Doron.
What we call a tautology is a statement that is always TRUE regardless of the TRUE of FALSE values contained in the statement. In its simplest form (X = X) is a tautology since it is TRUE whether X is TRUE or FALSE. Your “ontological level of T's self-reference” is just your own nonsense based on your own circular reasoning.
For a clearer understanding do some freak’n research.
It is not based on your circular reasoning and incorrect ascription of “self-reference” it is based on the simple fact that (X = X) is always TRUE regardless of the value of X.
Well that makes your “ontological level” self-contradictory as (F=F) is a TRUE statement and as much a tautology as (T=T) or (X=X).
(F=F), (X=X) and (Z=Z) are also TRUE statements as well as tautologies.
(F≠F), (X≠X) and (Z≠Z) are also FALSE statements as well as contradictions.
Once again you simply employing your favorite pastime of underlining everything does not suddenly or magically imbue your claims with any validity or meaning.
No, contradiction is specifically the negation of a tautology meaning it is a statement that is always FALSE regardless of the values in that statement. (X≠X) is always FALSE just as (X AND ~X) is, no matter if X is TRUE or FALSE.
Your inability or simple unwillingness to understand these simple and basic concepts has resulted in you making such ridiculous and contradictory claims as “Belongs AND does not Belong”.
Doron it is the creation of your fantasy “levels” (along with your lack of any comprehensive research) that results in you spouting your “gibberish”, which can be seen all along this thread in your posts.
Which simply makes your "ontological level" contradictory and inconsistent with such comparative assertions like = or ≠. It would seem that you simply do not understand that in using = or ≠ at your "ontological level" you are still, well, using them. Attempting to separate such use by claiming it is not “of the "used level"” is just your typical nonsensical “gibberish” resulting from you just imagining these self-contradictory and self-inconsistent “levels”.
Doron you simply claiming you are not using such comparative assertions while you are using them again only demonstrates you are simply just deluding yourself. Your only claim is actually that you are using them differently and thus inconsistently.
Doron consistency is a “core of Logic” and you are simply claiming your “levels” of “Comparison” are just inconsistent.
I must say Doron, using = and ≠ to show or claim that you are not using = and ≠ is certainly a new level of self-inconsistency and self-contradiction, even just for you.

Since you are able to get things only by T,F terms, you miss the ontological core that enables them in the first place.
So let us try another way to understand the ontological core of Logic.
By ontology we ask "what enables a thing before it is used for some purpose?”
For example, we can ask:”What enables Negation?”
The ontological answer to this question is as follows:
Negation is based on the ability to compare different things, such that ~X is anything but X.
It means that there must be some other thing, which is ~X that is comparable with X, otherwise ~ is on X and the result is nothing at all.
In that case we ask: “What enables X as a researchable thing?”
The ontological answer is:”X’s sameness-comparison”.
X’s sameness-comparison is a unary connective of a thing to itself, notated as =X, where "=" is the unary connective and X is the element.
Y’s sameness-comparison is a unary connective of a thing to itself, notated as =Y, where "=" is the unary connective and Y is the element.
Negation is difference-comparison, and therefore it is binary connective of X with Y.
Without Negation as binary connective of X with Y, X or Y are isolated of each other, and each one of them is closed under “=” unary connective of sameness-comparison.
Pay attention that that at the ontological core of Logic True or False concepts are not found, simply because True and False are some particular cases of Sameness\Difference Comparison, where Sameness\Difference Comparison is their ontological core.
Here is a representation of the ontological core of Logic:
that can be notated also as =X ≠ =Y, where "=" is unary connective of sameness-comparison and "≠" is binary connective of difference-comparison.
Again, True and False are not found at the ontological core of Logic.
The buliding-blocks of the ontological core of Logic are Relations = or ≠ connectives, and X or Y, such that = is non-local w.r.t X or Y and ≠ is non-local w.r.t =X or =Y.
In other words, the ontological core of Logic is based on Non-locality\Locality Linkage.
The Man said:
No, contradiction is specifically the negation of a tautology meaning it is a statement that is always FALSE regardless of the values in that statement. (X≠X) is always FALSE just as (X AND ~X) is, no matter if X is TRUE or FALSE.
Your inability or simple unwillingness to understand these simple and basic concepts has resulted in you making such ridiculous and contradictory claims as “Belongs AND does not Belong”.
1) At the ontological core of Logic TRUE or FALSE are not found.
2) “Belongs AND does not Belong” is exactly the non-locality of "=" w.r.t X or Y, or the non-locality of "≠" w.r.t =X or =Y.
