A significant percentage of the US is descended from those who abandoned the life they knew to move across an ocean because they were so afraid of a neighborhood or government conspiracy to murder them. For example: My wife's father's family. The relatives that didn't flee Europe were murdered in the early 1940s by a German government conspiracy.
