This is a question that I want to ask the hundreds of backpackers from Europe, North America, and Australia who go from hostel to hostel, drinking absurd amounts of beer, only mingling with one another, and eating Western food for every meal. I am staying in the Hanoi Backpacker's Hostel, which is cheap, comparitively, at 125,000 VND per dorm bed (about $7.25), and the way people travel at these hostels is sickening. They have no respect for local norms and etiquette, they are afraid to try local food, and they are generally ignorant of pretty much everything outside of the Lonely Planet guidebook and what their Australian hostel owners tell them.
Yes, I'm being harsh. But I'm sick of it. When I tell other westerners that I'm from the U.S. they get this look on their faces like I'm evil, when they're the ones dressing completely inappropriately, yelling drunkenly down the street, and slugging bottles and bottles of booze without any respect for how people actually live in the country that they're actually in. This is not Disney World! This is not an amusement park designed for Western consumption, though so many treat it this way. I'm repulsed. I'm repulsed by the Canadians who sew the Canadian flag patches on their North Face backpacks so that people don't mistake them for Americans, even though they're the ones behaving completely horribly abroad. I am repulsed by the British people who only visit British/Irish pubs in Vietnam. And I would be repulsed by the Americans, except for the fact that there are so few of us traveling these days, with the plummeting value of the dollar and the fear our government has instilled in us. But I would like to hold up a mirror to all these non-American Western others to show them the ugly ugly faces they display to Southeast Asia. It's disgusting. And it's across the board. I've witnessed rude Spanish people, offensive Brits, obnoxious Australians, scantily clad Canadians, oblivious French, and Dutch people who refuse to eat anything remotely associated with Asia.
Why leave your country? Just sit in your living room with a group of international students (meaning those from Europe and N. America) from your local university, turn the heat way up so your face gets glossy the way it does here, and drink yourselves into stupidity. You can play the same bad Western music, eat the same boring Western food, and pretend you're so so worldly. Just don't expose the rest of the world to your inconsiderate antics and nauseatingly oblivious behavior. It makes us all look bad.
