"They" did not necessarily fail. They were Co-opted by evil forces that had a very different agenda.
i think a couple of positive things did emerge from this train wreck.
1) men, generally, are now more aware that there IS a sexual harassment/abuse problem that MOST women have experienced.
2) Women, generally, now realize that if they are seriously abused, they need to TELL SOMEONE in authority--either the cops or the school/work. If they keep it silent for decades, no-one will believe them later on.
3) There needs to be a DISCUSSION about male/female relationships. Men, being horny dogs, are going to continue to try to get laid. Not every flirt from a man is sexual harassment! It is human nature for this sort of interaction to take place. So there needs to be a renewed effort to COMMUNICATE. THAT is where the ongoing discussion needs to be going on. If some guy at work compliments a woman he likes on her clothing, and she screams RAPE! to HR.....Well that is NOT moving things forward at all. Communication and understanding is needed from both sides
