The tone was cemented by you well before my most recent reply.
Several of the most popular shows in the US are UK knockoffs right now, so I could easily say that we are influenced by UK culture.
Based on my experience, I would dispute your claim that most non-Americans know more about America than Americans, and your heavy reliance on stereotypes and internet fodder, despite your stay here, is a prime example of that.
When your country spans a large part of an entire continent (and you could travel to the other countries on that continent until recently without a passport), are you really surprised that most Americans don't hold a passport? If we needed passports to travel between states, the percentage would be much higher I'm sure.
You clearly managed to pick up just enough to knowledge about America to spew out an seemingly endless stream of disparaging comments, so congratulations on that. Also, I found no evidence supporting your claim that 30% of Americans can't find the US on a map. Here's one article that I turned up quickly: http://blogs.news.com.au/news/splat/...rica_on_a_map/
Even if only 3% of Americans can't find the US on a map, that's not something to be happy about, but your eagerness to stretch the truth or pass along unfounded rumors in the name of some good old America bashing puts your true motives and feelings on display, and understanding America isn't simply a geography quiz.
You've discredited yourself by relying on general stereotypes rather than data, or even personal experiences since you spent some time living in the US. Why would you do that, unless you were only interested in bashing the US?
I agree that that a discussion of American culture (both its pros and cons, of which there are many) would be interesting. It's becoming apparent that you aren't willing (and possibly not able) to have that conversation, which is unfortunate and surprising given your time here and the fact you seem to feel quite knowledgeable about the topic.
