In the United States, the immigrant experience occupies a very central place in American mythology. And sometimes, that place wavers between acceptance and rejection.

Every new refugee to a society, whether it's the United States or some other place, is subjected to fear. They are the new outsider population, the new other.

Refugees have been displaced by war or natural disaster or political catastrophes, and they are much more threatening because they are reminders to people that all the comforts that we take for granted can be taken away in just a moment.

People may be vaguely aware that there's suffering in Iraq and Afghanistan, but simply because the media are filled with American-centric versions, we still see the experiences through the American perspective. We are just completely ignorant of what might be happening to other people.

I've never stopped being a refugee.

40, 50 years ago, Americans - the majority of Americans did not want to accept these Vietnamese refugees who they saw as completely foreign. Now there are new foreigners - Syrians and other people from the Middle East, people of Muslim backgrounds. And the sense among many Americans is, well, these people are completely different from us, and they're not like the Vietnamese who are much more assimilable. And I think that's very, very doubtful. I think that the majority of these new foreigners, if given the opportunity, will be able to assimilate and deal with American culture.

Refugees are threatening, not just to Americans, but also in many countries the world over. And it's partially because, unlike immigrants, refugees do not choose where they're going to go or why they're fleeing, and they are unwanted populations. They bring with them the stigma of disaster.
