I'm the one who mentioned adding Sally Ride. The reason is that the women listed were all feminists like Margeret Sanger. I can see adding Susan B. Anthony, but that is about it.
To many women, Sally Ride is a much better example of what the women's movement should be all about. Considering I have 2 young daughters, they know who Sally Ride is, but they have never heard of the other women on the list.
The other woman I would add to the list is Helen Keller. She did become a socialist, but she has probably been one of the most influential persons in our country advocating for people with special needs.
I would rather see Sally Ride, Helen Keller, and Clara Barton on the list instead of Eleanor Roosevelt, Margeret Sanger, Rachel Carson.
Alas, "exemplary" ain't synonymous with "influential."
