They've historically only been tiny immigrant populations that did slave labor and you never heard their complaints because they were so few in number. 

Today they flood in like any other population of migrant leeches and fail to even attempt to assimilate. Last I heard we got more Asian immigrants per year than hispanics. Only real difference between them and spics for example (since Asians vote similarly to spics now) is some Asian immigrants are rich and pay for their kids' college here. Then you have California schools admitting an inordinate amount of Asians, who are now overrepresented relative to their ability. Many Asian immigrants can't speak English at all and have zero regard for cultural norms or etiquette. They're bafflingly rude, unlike any other kind of immigrant. I can't tell if they don't care or if they're just unaware. I think the Malthusian conditions they have in Asia are etched into their DNA.
