Got it - in your opinion understanding the technical aspects of how Tell-A-Vision works (technically), is far more important than understanding the sociological, physiological, economic and environmental impact that Tell-A-Vision and 9/11 has had on our lives.
The world is very fortunate to have men of your great intellect gracing our presence.
It is indeed.
Television (I know you think you are making a clever point by butchering the English language, but you are not) is something that is a presence in our lives at the moment.
Most of what you have been talking about is an event that happened in the past. While it does have impact in the present, studying the events leading up to it has very little utility in my life, and in the lives of the vast majority of the people on the planet.
You have not actually answered my question: How would knowing the truth about 9/11 improve my life?
