Went to your linked site with an open mind. What I was expecting was facts. Was surprised and disappointed when a link about "secret government warehouses" took me to a video of the SciFi tv show "warehouse 13". Is this a joke?
I was very disappointed in the 911 link about Explosive Demolition of the Twin Towers.... I have no CLUE where their supposed "Experts" were trained, but their conclusions, are closer to Science Fiction, that to any Reputable FACTS..... My Opinion.... YMMV.....
That's why "truth" and "theory" shouldn't be used interchangeably. "Documentaries" have taken a dive in recent years.... I blame YouTube. No credentials or validation required. Theory - a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact.
True...but, credentials and validation are not indicative of quality programming. Michael Moore and Gore's "An Inconvenient Truth" comes to mind.
