Also people don’t think the best hope for their 7 year old is to send them away without their family. If you’ve got a 15 or 17 year old son who you think might be forced to fight as a soldier, you’re more likely to send them off to a far away relative. Or if you’re a teenager whose family have died, the same.
In the 90s there were a group of Kosovan boys who were sent away by their families in the same circumstances, and put up in my hometown as a temporary measure. People treated them like total dirt and started using the word Kosovan as an insult like it meant scum. It was really depressing, even though I already knew there were a load of knuckle-dragging EDL/UKIP types there (hey, they even voted in a UKIP MP).
