Let's take the "grabbing by the pussy" Trump. Why is that shocking ? Do you think Justin Bieber can't grab the pussy of one of his fan girls ?
If you don't see innocence in the scapegoat, we go back to our old ways of literally crucifying people. Once you see the innocence you can think of alternative ways of dealing with the problem, instead of killing and shunning people.
These oppression schemes have been around for ages upon ages. Witness the gospel accounts of the crowd chanting "Crucify him, crucify him" about a particular outsider troublemaker a couple of millenia ago.
Social media amplified the movement. And social media called the oppression to the carpet. Is #metoo a violent mob scene? Is it the same dealio as the stuff on Facebook about attacking the Rohinga in Myanmar/Burma? Or the stuff on radio about the Hutu-Tutsi violence in Rwanda? Those are hard questions to answer. I personally don't know.
I suppose it's up to us all to stop short of exacting revenge, while insisting on justice. That's probably the hardest task ever to confront humanity. We gotta try.
