A religious fanatic views contrary opinions as lies

Context: "Jaden Ivey says it is sinful for a man to lie with another man, says no one can stop him from speaking the truth. Ivey accused the Bulls of lying when they claimed his conduct was "detrimental" to the team."

It's only a *lie* if the Bulls truly believe that Ivey's conduct was *not detrimental*.

If the Bulls management truly believes that Ivey's conduct *was* detrimental, then it's a matter of opinion, not a lie.
