I'm trying to understand...
In USSR, they fed us lies for over 70 years - but we had no other information (for the most part, anyway...)
Besides, if someone came up with a different version of the "truth", they ended up in a forced labor camp, prison or mental institution...
But things very are different in USA (although for a while after 9/11 it seemed to slip closer to faschism) - you do not get persecuted because of thinking differently (for the most part, anyway).
So you see on TV 3 buildings collapse onto themselves, following the path of greatest resistance (the steel beams), and you are told it's because of the fire. Do you say "Hmmmm... Ok. It must be because of the fire." and then go on about your life?
Then you see 2 "crash sites" with no visible remains of any airplanes or airplane parts. You are given no explanation as to the disappearance (evaporation?) of the fuselage and the huge titanium alloy engines. Do you even begin to question what you're told?
