As to what "truthers" and "non-truthers" believe: I believe -- I have seen/heard this type of remark many times -- that a very large percentage of "truthers," me included, were very uncomfortable (e.g., sick to their stomachs) when it slapped them in the face that what they have been told bears no resemblance to what they now understand. When our minds conclude that the official story ain't all its cracked up to be and that leads to ghastly implications, we are faced with but one choice: either accept it or, if possible, ignore it. What I am saying is no, its not that we "don't want to" understand, its that now we do understand; of course most/all of you on this thread understand it differently. It is not easy to deal with the upsetting of our apple cart of beliefs in the way the world works; in what we have been told/taught all of our lives. In sum, we ("truthers") want to believe what our minds tell us. For example, I wouldn't "want" to believe in something because it is more "appealing" but doesn't make sense. From my perspective, if I did, my mind would be, well, screwed up: and that is not appealing.
If you would, could you point me somewhere regarding the chimney. Thanks
