Short terms shocks have reactions. Many of these things were already going in the right direction. 100 years of freedom (or no WW) between 1914 and now would probebly have been better for these groups.
Possibly, but there are numerous examples of minority (and majority in the case of women) groups agitating for the rights that they deserved, and in many cases having the dominant groups support them. I don’t think the social change would have happened at the same rate without the wars.
