I recommend watching at least one of these
Zeitgeist The Movie:
Part1:(without intro) http://video.google.com/videoplay?docid=-8461754114455236037
Part one shows the parallels between Christianity and several pre christian sun worship pagan religions.
Part two is about the twin towers and I'm kinda bored of the twin towers.
Part three is one of the most entertaining attacks of the economic I have seen. I would love to hear other peoples opinions about this part particularly.
The website is here It simply states that the film is intended to trigger peoples own search for the truth and that the movies are not finished.
And this is a great example of how the medium is the message
