The most amazing aspect of the anti-immigration cult is its monumental myopia. The United States faces a number of grave threats, one of the major ones being radical jihadism. While this movement represents a relatively small number of the worldwide muslim population, it is very well funded and led by shrewd and well educated (many in the United States) ideologues. Jihadists are not merely anti-American, they are profoundly hostile to democracy and individual liberties. They are not interested in negotiation or compromise, only in their aim of the complete destruction of all gubmits and subjugation to their theocratic caliphate. You might think in the face of such an inimical, existential threat, all Americans would welcome cultural allies of the same religion interested in upholding and assimilating into a democratic, capitalistic society with a rapidly aging workforce and expanding armed forces. But no.
