In other words, some stuff which I've always considered pretty self-explanatory. But you know, a lot of people I know (even *smart* people!) seem to still think there's some merit to these ridiculous, impractical theories. It would be amusing if it weren't so sad - the minute an authority figure tells them something, it's "don't believe everything you're told!" - but if it's from a homemade video by a college dropout, well hey, that's a valid source.
