When Albert Einstein came to the U.S. to escape persecution by the Nazis, prominent Americans like Charles Lindbergh were warning the nation of the dangers of letting outsiders into the country. He and many popular politicians, religious leaders and businessmen (like Henry Ford) got on the radio, lobbied politicians, published antisemitic books and pamphlets and joined with white supremacist organizations to spread fear and hatred toward Jews. Many said that Jews were communist agitators without morals who would infiltrate the American way of life, degrade American culture and destroy Christian values. So this supposedly Christian nation turned away Jewish refugees out of irrational fear based on a lack of understanding of others’ religious and cultural beliefs. And it’s happening again. One state government after another is shutting its doors to Syrian refugees, describing them as dangerous jihadists and assuming that Muslims are all wild desert people without morals. ISIS/ISIL/Daesh wants a religious war, and we’re playing right into their hands. Don’t let us harden our hearts against refugees based on irrational fear. Don’t let the terrorists win.
