Words have meaning. When words spoken are divorced from their actual meaning; when there is intent to mislead by the speaker, or insanity and inability to grasp real facts, people are harmed. Anyone that compares your actions and words will discover they can believe one or the other, but that they are mutually contradictory.
I think of serial liars sort of as wounds desperately slashing at those that come within reach, to spread their misery as widely as possible. Being void of integrity is evidence of void of meaning. When your words have no meaning, or are intended to mislead, the speaker has no meaning, or only means harm.
Tasmanian Devils have a face cancer that is reducing their population. It spreads, one actual organism, from face to face as the ornery devils bite each other. Lies, meaningless words, and profiteering have the same impact on society as that cancer has on devils. Those that are afflicted with it spread it to others, and eventually are removed from society because of it.
The cancer will not outlive the devils. Your recommendation is the equivalent of a terminal diagnosis. Please never recommend anything that matters to me. Never like anything I do. I don't want them to be diminished or destroyed by your toxic impact, the affliction of your care, that surrounds you and saps the vigor of everything you get near.
