Where did it start? It started right here. And this is where it could've been stopped! If those people had stood together. If they had protected each other, they could've resisted the Nazi threat. Together they would've been strong. But once they allowed themselves to be split apart, they were helpless. When that first minority lost out, everybody lost out.
