It's really not fair to read this in the context of today's political correctness. You have to read this in the context of 1955 history and what had just transpired in the world, and what was happening in the world. Just like today, 1955 America was a very paranoid place. Anyone who was "different" was suspect, whether they were a foreigner with a trunk full of cameras, or respected actors and actresses, ballplayers, and other public figures.
