Most of all she was a champion of equal rights. Not just for women and minorities but also men. Indeed I once wrote her to state that the best path to eliminating discrimination against women in society was to focus on discrimination against men as much as women. As I have often said, we will never see women making up half our political and business leaders until they also make up half our military deaths and alimony payers. (although eliminating alimony entirely would be better and everyone wants fewer military deaths)
The most iconic memory I have of Ginsburg is when she said her exercise routine included push-up. Not girly push-up but real ones. She was in her 80's at the time. Amazing.Her passing is sad especially now so close to the election.
