PROBLEM: Review: The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: Very disappointing read. Starts with her tale of what she saw in 1963 then devolves into another "MASSIVE GOVERNMENT CONSPIRACY" work. Offering no documentation to support statements made. Unsupported statements about what her boyfriend said, claimed or saw. Lauds Garrison and his persecution of an innocent man in New Orleans. Originally I thought &#65533;The Assassination tapes&#65533; By George O&#65533;Toole was the worst effort in Conspiracy volumes but no more. 
 Polarity: Negative

SOLUTION:
True
