You have switched the meaning of “absolute” with that of “relative.”
Absolute means external, objective, never changing truth.
Relative means internal, subjective, transient assertion.
The only benefit to pretending relative truth exists in place of absolute truth is to set the stage for the purpose of lying. In an imaginary world where truth is only relative (subjective), there’s no such thing as lying.
As I pointed out to you earlier in our semantic exchange, assertions of relativism are themselves presumed to be absolute although the speaker very often doesn’t realize it.
As I mentioned before, I’m not sematically inclined. I really don’t care about definitions. I am merely stating that when it comes to more than one individual, I simply do not believe a moral/spiritual/metaphysical/whatever one chooses to call it, truth, exists.
