I think the "insult" is partially fueled by a western superiority complex. I can't even begin to describe the panoply of emotions that I feel when someone tells my (naturalized) parents to "go back to where you come from."
In the coming years, *should* the "Eastern" countries become stronger, it will be interesting to see how perceptions of cultures are tolerated.
In Taiwan, the big swinging d*ck imperialism of the United States is felt greatly--the perception that the USA is a great country and that "we should strive to be like the USA" is very strong. In fact, so much so that English language classes are taught along side Math and Geography.
Is this a legacy of Western dominance post WWII and imperialism? When a country is so strong that it makes sense to be inviting to them? I don't know.

More on this later. Have to get up at 6:30 in the morning. (For a shotgun match.
