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.
To be perfectly honest with you, there's some truth here, but I'd like to clear up some things.
1.)For one, the popularity of eugenics peaking in the '20s & '30s IOTL was more of a perfect storm than anything else; it easily could have not become quite as prominent.
2.)The actions of the Nazis no doubt exposed the horrors of the most extreme kinds of racism, true, but as others have pointed out, the Civil Rights Era was actually really boosted by public exposure, particularly thru the medium of television.
3.)As
@Carl Schwamberger pointed out, the idea of independent women wasn't exactly new in the '50s-indeed, a trend towards independence had developed earlier on.
