What secret are we hiding? Well, it's awkward, and kind of embarrassing. You see, we're afraid. Terrified. This big, brash wealthy country. We have an irrational phobia. We're afraid of strangers. Not rich strangers. No. The ones who frighten us out of our wits are the poor strangers. People displaced by war and persecution. We're even scared of their traumatised children. And if they flee their war-torn countries in boats, well, then, they're twice as threatening.
