Tourists - Is it the right word?

Tourists?
We call them "tourists", the curious, kind of greedy people who go tromping through other cultures, usually not without bad effects. Maybe we should look at the world of tourists and decide if "tourists" is the right word to use. When I think of tourists, of course I imagine the often loud-mouthed ugly Americans in Bermuda shorts, Hawaiian shirts, with a camera dangling around their neck who devalue others' culture. I think of the British who swarmed India and other so-called "exotic" places to the detriment of the native population and environment. I think of the young Germans and other Europeans who have trashed the foothills of the Himalayas. I could go on but it would take too long. I suggest, though, that we find another, more realistic, less euphemistic term.
