> Please do provide evidence of this. Most people I've seen being surveyed in Europe around tourists don't care where they come from, as long as they spend money and don't ruin stuff.

There are a lot of Americans, they have a lot of money to spend and they like to spend money on travel. Isn't this sort of a self-refuting point?

I suspect people complain about the most common tourists, since they'll be the most visible.
