Majority of people around the world understand the wide variety of Americans that exist. Funnily enough, nowadays the Americans I come across in Asia are often more decent than other westerners. It's as if they are very aware of themselves and what they represent, since their culture is laid out for viewing for everyone around the world. But of course, these people are more intelligent and open minded than the average, they travel and seek new experiences whereas the one-liner ET Trump supporters probably never make it further than LA or NYC.
Personally I wouldn't want to be on an American passport for a variety of reasons, mostly practical like yours.
Coming from a tiny country, I have never quite understood or experienced the feeling (typically not real) that comes from knowing that you have 200 million or more people speaking you language and sharing a society. Although based on my experience with Russians, I think the effects of this are adverse.
