Although the Jews, gays, gypsies and retards suffered the most during WW2, don't forget about the 'normal' citizens who nearly starved to death, like my mother and her family who lived in the cities in Holland. The people in the country had enough food to keep them from starving, but not city people who risked their lives to get some veggies or even flower bulbs from the fields. My mom's family ate their cat and dog in the end to survive and had a nightmare scenery puberty which gave me a scar or two when growing up, listening to her horror stories, her uncle was hung in city square and they were forced to watch him choke, all he did was trying to find food for his sick children after curfew time. There are so many horror stories from the non-Jews too, also in Poland and Russia, they suffered terribly. A global study should be performed.
