If you redefine words to mean whatever you want then yes, black can be white, but it destroys language as a means of communication.
Subjective = “influenced by or based on personal beliefs or feelings, rather than based on facts”
Objective = “not influenced by personal beliefs or feelings”
They are antonyms.
It seems to me that you have left out of your accounting that there are many meanings of “subjective.” The first one of which (below) pertains to what I have been saying. The third and possibly the fourth, to what you have. The dictionary (Merriam-Webster,) it seems, gives priority to mine by giving it prime of place (1b).

a obsolete : of, relating to, or characteristic of one that is a subject especially in lack of freedom of action or in submissiveness

4

When someone is making a truth claim such as "That painting is beautiful!’ what they are doing is making **the painting **the “subject” of their truth claim and saying something they believe to be true about the painting.
Subjects and objects are semantic aspects of language. In English, because it uses an SVO (subject verb object) language structure, the subject (who or what the speaker of the statement makes a claim about) typically opens the sentence. The object is the “receiver” of the action (the activity designated to the subject) because the object "receives” the action (verb) of the subject. "The cat [subject] ran [verb] to the tree [object].
When “is” is used as the copula, the object of the sentence is “about” the subject in the sense that a truth claim is being made about the subject per se. “The painting IS beautiful.” is such a claim. Notice that painting is both the subject of the sentence and an object in its own right. However, a sentence like “I like strawberries.” uses a subject (in the sense of definitions 3 or 4 as the grammatical subject of the sentence.
This is where you have become confused. You assume because a subject can be a subject semantically in a sentence, then all statements with subjects as subjects become subjective. Are you confused yet? You likely are because your response shows you haven’t thought enough on this subject.
To say, “That painting is beautiful!” is to make an objective claim ABOUT the subject (the painting) of the sentence that is, objectively speaking, the object of the claim.
To say, “I like that painting!” is to make a subjective claim (like) about a subject (I) that is coincidentally also the subject (in the sense of definitions 3 and 4) of the sentence.
Just because some people don’t know the meaning of words doesn’t mean we must all give up on language.
If beauty is objective then there would necessarily have to be a way that is independent of personal feelings to compare the beauty of one of Pink Floyd’s ditties against something else. All I did was to ask (several times) what that procedure is.
Instead you keep responding with arguments from obfuscation. By redefining “subjective” to give it a private meaning, you conflate it with “objective” such that war is peace, freedom is slavery, and ignorance is strength, as the slogans on the Ministry of Truth read in Orwell’s 1984.
So, in summary you made a claim and until you substantiate it objectively, “beauty is in the eye of the beholder” stands tall.
Clearly, from above, I am not using private meanings, but attempting to sort out the obfuscation by using the full range of meanings which you conveniently have ignored to make a trivial point about only one (or possibly two) of the meanings.
My point has been that both subjects and objects can be the subject of truth claims. Where an actual subject is the subject (I like…) the truth claim could be merely a statement of preference with the sole arbiter being the actual subject of the sentence in both senses.
However, when the truth claim is ABOUT any object (a tree, a painting, a food) the proposition is assumed to be an objective claim about the object. “This fish tastes salty!” is an objective claim subject to verification. "I like this salty tasting fish!” is a preference claim which can be verified by only one subject - the one making the claim.
“This painting is beautiful!” is NOT a preference claim, it is an objective claim made ABOUT the painting subject to analysis and judgement as to whether it is meaningfully true. You cannot wave it off by claiming it is MERELY a subjective claim. It doesn’t semantically purport to be subjective since it is being made ABOUT the painting, not ABOUT anyone’s feelings or preferences in the way “I like that painting!” is.
