You lay it out for Sam. As far back as records go, the Spillanes have always been poor white Irish. But you don't need to belong to a group to empathize with their struggle. You've never had any truck with the kind of crude white supremacy that the Nazis espouse and that is so common back home in the South. Your own ancestors were treated like dirt back when they first came to America, written off as lazy, drunken, criminal Fighting Irish, and exploited through indentured servitude and starvation wages. There's no excuse for their descendants being complicit in treating others the same way.
"There's nothing you can do about it," says Sam. "You can't control what someone like Schneider sees. You know your own heart, and that's what counts."
You get to your feet and look around the camp. What do you want to do now?
