I think we agree, the US is one sovereign nation, and Europe exists out of 50 sovereign nations. I never said that the US was homogenous, just that Europe was less homogenous. I love the US, even had an American girlfriend for a year or so. I've traveled across the whole country, and every state is different and has to offer different kinds of food, nature, etc. Hell, I'd like to move to US in two or three years.
I did travel through Texas a couple of years ago, and I have to say, some of the nicest people I've met in the US were from Texas. I had planned on celebrating 4th of July in Austin, but because of some transportation problems I ended up in one of the smallest towns I have ever seen, and had the best time. Everyone was so hospitable!
