Great insight! Your story is spot on. One reason humans are so successful as a species is because they form groups and cooperate. Exclusion from the group could be life-threatening back in the day, and is an effective way to change behavior. Exclude the rapists and men will stop raping. That's why #MeToo and high profile rape cases like Bill Cosby, Harvey Weinstein, R. Kelly, and Larry Nassar are so important and (hopefully) changing rape culture. Maybe the next time Frat Boy sees a girl passed out drunk at a party he won't think it's okay to rape her.
