David Neiwert writes about it here. I'm not sure I have much to say that he hasn't, but from my experience racism against Asians and Asian-Americans is quite pervasive and almost universally ignored. As David notes, it takes a different form than racism against African-Americans, which for some reason "makes it okay." In a way, however, the racism against Asian-Americans is even more poisonous. To the vast majority of people in this country, Asian-Americans are "foreigners," even five generations later.
And, make sure to check out the next post where David discusses Sgt. Stryker's rather bizarre attempts to whitewash Japanese internment. At the end David asks the money question:
Does wartime justify the suspension of the basic American right to a presumption of innocence?
Civil libertarian Glenn Reynolds has said yes. Civil libertarian Atrios says no.
