Viewing the world in black and white is a common feature of childhood, and sadly, many of us never outgrow it.
Easing arbitrary national boundaries will not lead to dark savage beasts despoiling our pure Aryan daughters, or Middle Eastern extremists exporting their explosive brand of gospel across the world. The new world order is not going to enforce homosexuality or stamp a '666' on your forehead. Get over your petty fear of the dark.
