It's very important to understand the difference between being complicit and enabling a predators behavior vesus being yet another person who was manipulated by that person.
I know lots of people are beating themselves up over this stuff and wishing they could have done something or connected the dots but that's how these fuckers work. They manipulate and surround themselves with good people to shield themselves from criticism and suspicion
"He has never done that to me!" I have never seen him be creepy" "He has helped my career so much". This is how they get away with this shit for so long. They build a network and power and hide behind it. They pick and choose who they want to be awful to.
The sooner we realize that people we love and care about and think we know and understand can be completely horrible monsters around other people, the better. This is mainly something us men need to remind ourselves.
