Mark Perry uses the Venn diagram to great advantage in a post for the Foundation for Economic Education.

Thanks to John Venn, I now have a part-time job as a Venn diagram graphic artist/specialist – they are a very effective way to illustrate graphically the intellectual inconsistencies that are widespread and commonplace among the public, especially with our left-leaning friends.

Venn Diagram I (above) on Al “Bigfoot” Gore’s hypocrisy when it comes to his YUGE carbon footprint. Drew Johnson, whose report exposed the fact that Bigfoot Gore uses 21 times more electricity than the average US family, commented “It’s frustrating if you’re an environmentalist because Gore sets himself up as a prophet – but he’s actually a fraud and a charlatan. You’ve got to ring the bell of hypocrisy here. It’s like a religious leader cheating on his wife.” Note also that the report only covers Al Gore’s voracious energy consumption at his main 10,000 square foot residence in Nashville, where he apparently lives alone and does not include his other two residences.

Venn Diagram II (above) on those who support “Buy American” and “Hire Americans” in theory, but love to shop internationally and travel globally.
