1. Civil libertarianism. What other country allows anywhere near the amount of 'offensive', 'profane', 'blasphemous', or 'pornographic' content to regularly be published and widely accessible? What other country doesn't lock you up for saying the wrong words or thinking the wrong thoughts (mostly looking at European social democracies here, what with your 'hate speech' laws and all)? What other country has the kind of sustained, civil libertarian ethos that the United States has had since perhaps its foundation? I love the fact that in America there are organizations and people that will go to bat for you on any perceived slight of your rights. America is truly unique in this aspect, as its always been kind of the loud, irreverent stepchild of bourgeois civilization.
Meanwhile, European televisions can show nipples and use curse words.
