I think I might take the safe route and not include anything related to the Holocaust. It's a very dividing issue, and both sides of the coin are extremes. A "happy medium" is what the most people will enjoy.
As for the topic of eugenics, I'll keep that advance for the simple reason that many countries/societies across the world at the time advocated the idea of "bettering society through selection". It wasn't just Germany, Japan or Italy that practised eugenic ideals. Most of the developed nations of the world did, including USA, UK, France, USSR, Australia, China and Brazil. In a way, Switzerland had a strong eugenic movement too. The wonder I'm associating with eugenics, Social Toleration, is based on the understanding we reached due to eugenics that toleration of other nations/races/ideals is necessary to function in a global society.
In this way, I see it as recognising the driving belief of eugenics which led to Socialist Nationalism, while not trivialising the events that occured due to the beliefs. The Social Tolerance wonder should teach us that in this modern global society we need to work together, not against, to progress into the 21st century.
I hope this satisfies the masses.
