I want to add to the vocality of the Asian American community. Asians in the U.S. are still very much viewed as foreign. Those lychings of Chinese migrant workers of the 1870s is no different from the hate-based crimes today. The recent case of Dr. Wen Ho Lee, a nuclear physicist at the Lost Alamos laboratory is one example of racial profiling and scapegoating practiced by white Americans against people of color. Another tragic example is the murder of Vincent Chin, a Chinese American man who was murdered by two white auto workers who begrudged the Japanese automotive industry.
Chinese culture is acknowledged by many scholars to be the oldest living culture in existence.
Generally speaking, you cannot wipe out 5,000 years' worth of culture in one American generation, or even two, or maybe more. There is also a sense of cultural pride that Chinese people have. 5,000 years of history. The language is ancient, the traditions old and refined. These values have immensely contributed to the economic and social success of the Chinese diaspora.
