If you were to go to the site, you would see 911 truther crap and other tin-foiled hat conspiracy garbage that can/will never be proved.
"Truthers" present numerous things that are undeniably true facts, but that does not necessarily mean that their analysis is the correct analysis. Facts are useful things, but overreaching in your analysis can limit your ability to present your ideas in a good light. Don't try to supress facts, just because they May lead where you don't want to go; just be glad to have them, and save them until they come together to form the true picture.
