By it's definition, truth is not relative. But we make it so. We rationalize. We rationalize to make ourselves feel better, or more secure, or more important or whatever... We lie to ourselves.
We then expound our views to others. The more people that believe the same lie we do helps us enforce the lie we have told ourselves.
History has proven truth to be unpopular, even fatal.
This comment excludes the active reinforcement of another's lie. Example: "does this make me look fat"? You are not lying to yourself, but trying not to have the argument that will always ensue if you deny the lie of another.
If a statement is a misrepresentation due to ignorance, it is not a lie, but an innocent lack of knowledge of the truth.
