People who become this vehemently opposed to the issues are in some ways (as others have said) validating the 9/11 truth movement. Call me crazy, but I think some of these articles are created by design to serve this very function.
I remember when I was first approached with some of the 9/11 questions, and I'll admit I dismissed it immediately, but I wasn't pushed any further, and I didn't call anybody names for trying to show it to me, and the person providing their evidence simply let me be. No name calling, no blanket statements from either side. There wasn't any negativity expressed from either side on the matter because it was understood that exploring the subject didn't leave me with anything to lose, just something to gain.
This is the problem with people who express hostility towards those addressing the importance of these questions. They feel they have everything to lose when they consider the answers to these questions and the impact it will have on reshaping their belief system. They don't understand that pursuit of this matter will help them regain their freedom, and that the use of terror psychologically conditions Americans to be fearful of freedom.
These people need to understand that their belief system won’t necessarily have to be reshaped, only the belief in those people who’ve had control of that system. See, the system can be restored to empower the people again, and acknowledging the importance of these questions and seeking answers to them is the first step in this transition. But the people have to want it back. If they don’t, then things will continue as they are, and get worse.
