It seems to me a lot of the discussion following the San Bernadino shootings has talked of Muslim terrorists using the assumption that such terrorists are aliens to the U.S., ignoring the fact that one of the shooters was a native-born American.
On another subject, I'm struck by the growth of Asian Americans in the U.S. Back in the day we had Chinese Americans, Japanese Americans, Korean Americans, and the original Filipino Americans. Then we added Vietnamese Americans, Indian Americans, Cambodian Americans, Nepalese Americans, Bangladeshi Americans, Pakistani Americans, etc. etc. Now the great American blending machine is making them all "Asian Americans", whether they like it or not, ignoring not only the differences among the nationalities but also the differences within the nationalities.
