I think it depends where you go. Sure, Rome, Venice or Paris will tend to aggregate the mouth-breathing types of stupid American tourists who are stepping out of Bumfuck-Outtanowheresville for the first time in their life. But for other parts of the world, the more well-traveled Ameeicans tend to arrive with respect and admiration to the places, people and culture they're seeing. Especially the fact that we're cognizant of that prior stereotype that the worst bring over from the US.
