So, if you know what doesn't occur, what's the status of women and other minorities by the 21st century. I mean without the Holocaust, eugenics wouldn't have had a (well deserved) backlash and Racism would possibly be more acceptable as there wouldn't be an example of Racism's symptoms when people let it go out of hand. I also hear that the experience of women working in the ammunition factories really helped the feminist movement since it showed that women could more than just house wives.
