There's too much uninformed, and not to mention divisive and hence useless, banter when topic questions like this are posed. Here is a SCIENTIFIC survey of how many ethnic and racial American subgroups feel about each other when it comes to intermarriage. It is quite telling since you really know how a person feels about you if they want to be related to you or not.
http://www.mercurynews.com/multimedia/merc...y3_marriage.jpgIt is as I expected. Filipino's are most popular, then followed somewhat distantly by the Chinese, then Asian Indians, then Vietnamese. But why we Vietnamese come in last is due in large part to the many stereotypes placed upon us during the late 1980's and 1990's when the Vietnamese gang problem was pretty serious. (On the flip side of course is that, we Viets were amongst the most likely to be the victims of hate crime committed by racist whites & "ghetto" blacks during the intervening years between 1975 and 1995, or so.) This image problem for Viets is changing in our favor now. Our social economic standing is relatively high now, and the gang stuff is for the most part gone. We're no longer ghetto. There may be a lot of nail shops and what not, but were producing too many md's, dentists, engineers, pharmacists, business majors, lawyers, and other professionals, to be considered ghetto. We're affluent.
Overall, I suspect that the Koreans fair somewhere around that of us Viets and Asian Indians, and that the Japanese fair better than the Chinese by maybe 10%. Koreans had a real image problem following the 1992 LA riots as being gun-totting proprietors of liquor stores in poor black neighborhoods.
Generally speaking uptight cultures don't fair well in these types of surveys. We're Confucian, just like the Chinese, Japanese & Koreans. But our image, and wrong it is, is that we were under-achieving ghetto Confucians. Japan is on top, and many Americans drive Japanese cars and own Japanese electronics--hence they are to be much admired for their economic & scientific dominance. (For now, I would say that the Japanese are the most culturally refined--in the PC, politically correctness, sense of all NON-white countries. However, they are not quite there yet.) Asian Indians in the US are typically the upper class Brahmins, which speaks for itself. They are a pretty uptight people too. Filipinos, on the other hand, have very high social economic status (only the cream of the crop come to America, like Asian Indians, Chinese, Koreans & Japanese), but they don't have an uptight culture like Confucianist Asians or Indian Brahmins. That is, Filipinos are a rich and easy-going bunch, which is why nobody minds having them join the family, i.e. intermarriage.
People respect shallow things like wealth. But they also respect good things like an easy-going attitude. Filipinos have both; Vietnamese have neither according to stereotype. We're supposedly both poor and haughty. The worst of both worlds. Of course, Confucianists and Brahmins, by default, lack easy-goingness. (Of course, people also prefer groups with low crime rates! Affluent groups have low crime rates.)
In the past, during the days of the "Yellow Peril", Chinese were hated. Post Pearl Harbor, it was the Japanese... Things change over time. We must always keep this in mind.
