You're welcome to take it anyway you choose; I can hardly stop you.
However as semantics is "the branch of linguistics and logic concerned with meaning", it's essentially all we've got if we want to communicate. And I'd have thought you, as a legal professional, would be well aware of the important and significant difference in meaning between what a person (or website) says of themselves, and what an observer says, while attributing it to them.
When you have clarified the meaning you intended by
your still unsubstantiated charge that Politifact claims its assessments are irrefutable truth, we might be able to have a meaningful discussion about Politifact. Or, alternatively about the propensity for exaggeration, overstatement and claims of unverifiable authority.
But not until. It's semantics, you see.
