No more than we teach "foriegner hate" over here. Both sides are guilty. Have you ever heard the term "Ugly American"? There is a reason that phrase is popular. Some of us can go over and give "uncle sam" a huge black eye.
I was in Lisbon last summer with my inlaws where a lovely (and I use that term loosely) young couple were literally screaming at the waitress for moving to slow and not speaking English. When I mentioned that they were in Portugal and that the national language is Portugese, they said "Well if they want my money, they should learn some english". Oh yeah, darlin' you are definitely endearing them to Americans. Had they read a guide book they would have found out that meals are very leisurely in Portugal. people take their time eating so a waitress/waiter generally will not stop every 5-7 minutes to check on you like they do here, that is seen as intruding or "rushing" you.
I also think that we go to other countries ignorant of the customs. Every one talks about rude Parisians but I find that they are not rude but very, very formal. they don't speak loud in public and speaking loud on cell phones is a big faux pas, some thing we yanks do all the time especially in inappropriate places (museums).
So buy a guide book and travel Europe, it is absolutely stunning.
P.S. I am by no means an expert, these are just my thoughts after a few trips.
