Suppose you'll take this the wrong way... but who really cares. Have fun spamming, OE.
Every man, woman and child --- some sooner than later --- develops a theory of life, an understanding of how the world works. Over time, our ideas coalesce into axioms, which Webster defines as needing no proof because the truth is obvious. Alas, public opinion has the power to twist a maxim or an axiom into a belief, which seems to be true or valid, but is in fact the antithesis of truth. We know this technique as propaganda, which is any systematic, widespread, deliberate indoctrination or plan for the spread of ideas or customs from person to person or generation to generation. Propaganda is generally used in a derogatory sense, connoting deception or distortion.
