I think we need to recognize that there is a difference between
discrimination as a widespread social practice and legal
segregation, a practice which has the force of law. The Supreme Court, in Plessy v. Ferguson, recognized Southern Jim Crow laws as constitutionally valid as long as the segregated facilities for non-whites were "equal" to those reserved for whites. The Brown v. Board of Education of Topeka, KS ruling reversed that and invalidated the underlying segregationist philosophy prevalent in so many jurisdictions. Did that end all discrimination? Of course not. Federal military force had to be used to enforce school integration at places like Central High School in Little Rock, AR and at the University of Mississippi.
Until Dys revealed that Asians had been barred from owning property in New Mexico until very recent times, indeed, I had always been under the impression that segregation and discrimination by law against Asian-Americans had been strictly a California aberration. (I'm not talking here about the Asian Exclusion Act, a Federal mandate which, on its face, at least, was intended only to limit immigration of persons of Asian extraction. It did not address the status of those Asians already living here legally.) The first Asians to come to North America (if we exclude the ancestors of the so-called Native Americans
) came here during the California Gold Rush of 1849
et seq.. They were not exactly welcomed with open arms. Others, mainly Chinese, followed these early immigrants and found work laying tracks for the transcontinental railroad. Indeed, the tracks for Union Pacific and the Central Pacific were laid almost exclusively by Chinese laborers working West-to-East and Irish immigrants, working East-to-West.
California enacted numerous discriminatory laws against this influx of people who did not resemble Europeans. Segragation of schools and other places of public accommodation became legalized. The Japanese, always in smaller numbers that the Chinese, bore as much of the hateful bias as any other ethnic group. And after Pearl Harbor, of course, the Japanese became the scapegoats and whipping-boys. There are entire towns in Hawaii which, before World War Two, were almost exclusively Japanese enclaves. Today you have to go through old nespaper files to find any traces of Japanese presence in these towns. Property was expropriated, the original owners sent to detention camps on the mainland, and now towns like Halualoa on the Big Island have perhaps one or two Nisei families living among all the white folks who moved in.
