Banned TED Talk: The Giant Ceremonial Astrological Mound Builders of Ancient North America

"It’s truly mind-altering to contemplate history, I usually start with the fact that most of our recorded history remains in secrecy. The US Government alone, according to some historians, classifies approximately 500 million pages of documents every single year.

"How can a researcher, historian, or anybody who is interested in diving into the archives of US history, for example, expect to find anything of any real substance that actually pertains to the truth? History is written by the victors, and most major historical events are full of information and facts that don’t really show up in our secondary and post-secondary ‘educational’ textbooks. These days, no matter how much evidence and fact support a topic, if that topic and information simply defies beliefs, or offends current upheld belief systems (many of which are based on lies), then it is rejected."

Much more at the link below, but I was frustrated that I couldn't watch the TedX video, so I did a search and found another that's still available, except for the last too many minutes (see comments pasted below) ...

The video goes bad as soon as he mentions how amazing it is how much of this the Smithsonian seems desperate to cover up.
