Yes, all this black-or-white talk about genocide misses a lot of the subtleties. How about a nuanced analysis of the Jewish Holocaust? Nobody brings up enough the fact that Hitler built some damn good roads.
The Germany that produced the Jewish holocaust also invented rocket science, which indirectly led us to the space program, satellites, and a big chunk of our modern communications network.
Does this excuse genocide? No. Does it make it difficult to label German civilization as "all good" or "all bad"? It absolutely does.
And since as a nation their positive moral acts was so little relative to their negative moral actions you can call them "bad".
You get into trouble by saying that in Germany my friend :)
I'm not suggesting that Hitler's good roads made the holocaust less bad. I'm suggesting that the Holocaust didn't make the good roads less good.
Things aren't either all good or all bad. That includes the Conquistadors, Hitler, the Nazis, your children, a puppy, the Na'vi, the Native Americans, and everyone else.
This does not mean that everything the German army did was good or justified (e.g. the Holocaust). And neither was the allies knights in shining armour (firebombing of Dresden and Tokyo comes to mind).
My grandparents (although not German citizens) were fiercely supportive of Germany in WW2, as where many people. This stemmed mostly from the UK’s treatment of people in its colonies.
