Zeitgeist blew my mind too. Anything with that much bullshit in it should come with a disclaimer.
The religious arguments are nearly TOTALLY wrong, not that I believe in the Christian story at all...
The political arguments... If you want to make such large leaps of faith and call it deduction go ahead.
The only thing that even shakes a stick at being correct is the fiscal information. Yet, even there you can tell someone's ignorance in economics when they're listening to stuff like Zeitgeist, Beck, Alex Jones because they then suggest gold as a financial standard...
As soon as someone suggests a gold standard I stop taking them seriously.
