Even though the vast majority of the other things you said were true?
This has nothing to do with FD, it's more to do with your view on things and some ridiculous "once a liar always a liar" theory or something.
Just like in court where the court doesn't declare you an unfaithful witness if you are caught in a lie. They just let it slip, and say "just because you lied on this item, doesn't mean that you may have lied on other things as well".
