“Certainly here in the U.S., we've had fundamentalist movements that have taken very critical and hostile attitudes toward immigration and the assimilation of immigrants into our society and culture. So these tendencies are fairly universal. The problem is what if they get out of hand and become the dominant factor in a society, which can only lead to the oppression of minorities or even to war with neighboring societies with differing cultures. That's why it seems to me it's important to try to keep these tendencies toward extremism under control.”
