Coincidentally, two bloggers that I read have both written lately about unsung heroes of the Holocaust - little-known people who resisted the Nazis.
Irina of the Ignoble Experiment writes about The White Rose, a group of students in Munich who resisted the fascist regime in Germany in a non-violent way. They unfortunately were caught and executed by the Gestapo.
Neo-neocon posts about an Algerian born Muslim in France who led a group that rescued Jews. He was the rector (the shamash?) of a mosque in Paris and used it as a hiding place.
It seems that dark times bring out both the worst, and the best, in people.
