I remember thinking this about Europe when they taught us the continents. My disagreement persists to this day. Europe and Asia are obviously the same continent and the distinction between them is arbitrary. I would guess that this easiest-to-accept of lies, since it is of no consequence to one's daily life, would be a particularly good starting point in the indoctrination scheme. These sorts of lies could gradually be added over time until we arrive at the bigger ones that relate to philosophy, the physical sciences and economics.
In retrospect, I can also note that my teachers' responses to these questions about the trivial matter of the European "continent" sound awfully similar to the responses I was given when questioning inconsistencies between the Bible and what we were taught in church school, or when I challenged my mother on the existence of Santa Claus. All of them essentially amount to "just do what I say." The one that bothers me the most is the Santa Claus thing, because it's so near and dear to people's hearts. It's a very well crafted propaganda tool used to generate conformity. I've never seen a better one for at least singling out what you refer to as Mustangs in this series.
I hope my essay has confirmed in you a dedication to the observations of your own eyes and senses in lieu of obedience to authorities that are provably lying to you. No better result of my considerations is potential than better enabling free people to grasp the reality they hold the power themselves to effect their destinies by attaining to decentralized means of production.
Decentralization is not a meme; not some fluke of coincidence, but the necessary evolution of technology that increases it's utility to humanity, by increasing it's profitability to individual people. Decentralization renders centralization obsolete, and eventually will completely supercede the power of parasitism that continually saps society to empower overlords. Be free, and by attaining to your own best interests enable your brethren to seize their own destinies from the vampires that seek their life's blood.
Thanks!
