One issue is that we generally notice the loud obnoxious stereotype, and there are enough Americans that fit that mould.

And perhaps you are discounting that many people make their own judgement call based on the interactions they have had with Americans.

I am not sure it has much to do with tourists per se. On the gripping hand, I am in Palma de Mallorca at the moment, which many Europeans travel to for the beach and party life: there are some definite stereotypes for the Poms and the Germans!

Every visitor faces bigotry, some fair, some unfair.

American's can get plenty of positive reaction too. At least most people have some idea about your country and customs from watching movies: try coming from a third world nation...
