We had an American starting a thread called "Why are Americans so fat?", and we had an Englishman starting a thread called "What is it with the English?"
The American thread was about world hunger, the English thread about hangups people have about folk music.
They both seem perfectly reasonable questions for someone to ask about their own country, and sensible subjects top have discussions about. Why should anybody see them as offensive or whatever?
I'm not being sarcastic, I just can't see what there is here that should get anyone upset.
