You're right, Davethedog.
The story is quite prophetic, from that point of view.
Or was it reflective, I wonder? Two decades earlier, one society (Nazi Germany) had come to accept one particular view of society as the "norm". With the benefit of hindsight, we wonder how such a huge nation could have been so taken in by such a philosophy, and we continue to hunt out those who accepted and followed it.
Interestingly, I wonder why we don't try to find survivors of old cannibal tribes and try them for murder? The answer is that they were doing what the majority in their own society considered to be an acceptable norm at that time.
We are quite selective in our judgments of others, aren't we, and we will always have a tendency to view our own values as "normal".
