I'd find this map funny if I didn't still meet many rednecks who think that the world revolves around the USA.
The culture, civilization, legal system, free economy and language was transported there from Europe just a while ago. For some weird reason lots of Lukes and Bubbas somehow visualize that these great things are all invented in the US... in a country that's just a few hundred years old for Chrissakes!!! I find that almost hilarious.
Nothing against America though... great country. I just despise the arrogant rednecks (regardless of their nationality).
