Bill;
What's this have to do with 9/11? Why don't you join one of the discussions of this in science or current events. They'll love you.
Because the way that this 'big lie' is carried out is exactly how the 'big lie' of 9/11 is carried out. You buy or intimidate your bunch of scientists to say what you want them to say, you have your compliant media print and broadcast what you want and in this way you control the thinking of most of the people for most of the time.
And last but absolutely not least you have your teams of debunkers to shout down anybody who speaks out against the official line. Do you recognise yourselves here guys ? lol
That is all you you need to carry the 'big lie' forward. Here are two paragraphs that encapsulate this.
"All this was inspired by the principle -- which is quite true in itself -- that in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily, and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods. It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying. These people know only too well how to use falsehood for the basest purposes."
"Most people prefer to believe their leaders are just and fair even in the face of evidence to the contrary, because once a citizen acknowledges that the government under which they live is lying and corrupt, the citizen has to choose what he or she will do about it. To take action in the face of a corrupt government entails risks of harm to life and loved ones. To choose to do nothing is to surrender one's self-image of standing for principles. Most people do not have the courage to face that choice. Hence, most propaganda is not designed to fool the critical thinker but only to give moral cowards an excuse not to think at all."
