A question for those who believe truth is not absolute

[robvalue]

It appears to be a contradiction in terms, so that the answer "yes" is paradoxical.

If we answer "yes", we have an absolute truth; but then the claim itself is that truth is relative and not absolute. So the statement cannot be true. It's like the Liar paradox.

This doesn't say anything much about absolute or relative truth, other than their incompatibility within statements.

I do see where you're going, you're saying "it's not absolutely true that truth is relative". But if truth is relative, absolute truth is a meaningless concept and so is irrelevant. Truth could also be some sort of mixture of the two.
