A person alone isn't a liar. Lies are told to closed minded people to avoid conflict and retribution. Who tells a lie to a truly open minded person? I don't. What is the need? I won't be judged or punished.
A closed minded person can't handle the truth, doesn't want the truth and will punish the truth. That person deserves the lies.
Closed minded people have a superiority thing about them. They don't deserve respect beyond basic human dignity.
