Is it true that there is no absolute morality?

[Nonpareil]

Show me anywhere that subjectivity is defined in terms of variable truth.

That is what "based on opinion" means, benny. It means that it is only true if you share the same basis for making the judgment of value. "La La Land should have beaten Moonlight for Best Picture" is only true for you if you share the same opinion about what makes a movie good.

Then, consider that this question is in the philosophy section, and discover that "subjective" has specific meanings in that context.

Yes.

It means "based on opinion; not true from every perspective".

 If you actually want to engage in a discussion about whether truth can be (or maybe MUST be) subjective, then we can talk about that.

I have never said, or implied, that truth "must be" subjective. I have stated, simply and plainly, that value judgments are, by definition, subjective, and as such, "objective morality" is a contradiction in terms. You then went off on a dozen incoherent rambles using definitions of "subjective" that have nothing to do with the discussion in hand, and continually failed to understand it when this was pointed out to you.

I am beginning to suspect that you went off on a tear against my posts while under the impression that I was arguing for something entirely different.

What's an opinion, and how would you differentiate it from fact?

An opinion is a judgment of value. It is based on opinion, and is only "true" inasmuch as you may or may not share the same opinion.

A fact is a fact. It is true regardless of your opinion.

This is not complicated.

I'd say an opinion is one's position on an issue which does not HAVE an objective truth value-- for example, it is my opinion that chocolate ice cream is the best, or that Abba is shit music.

This is correct. It is, in fact, my entire point. Judgments of value - that is, opinions - are only "true" so far as you agree with them. They are not objective. They are subjective.

As a non-truth-related opinion, "Chocolate is the best" is my opinion, and it may be said to be true subjectively.  OBJECTIVELY, given say brain scans when I eat chocolate or talk about it, you must refine your context: "It is objectively true that chocolate most stimulates those parts of the brain responsible for pleasure in bennyboy."

Again, correct. This is what I have been saying. This is the distinction that I have been drawing, repeatedly and consistently, throughout this entire discussion.

I am not sure what you think that you are arguing against, at this point.
