I've always been fascinated with the Holocaust and so when there was an interview with a Holocaust survivor on 60 minutes, I had to watch it. The woman said a bunch of stuff, but what stuck with me is that she said that, "people need to be given permission" to act badly. The episode showed previously undiscovered notes and pictures from one camp, showing officers having a picnic and enjoying themselves after a hard day of???

Her point was that these people were given permission. I now see it everywhere. Food fight in the school cafeteria? There were a few instigators who gave permission to the rest. A city protest that turns violent? Again, a few vocal minority of the group started the violence and then the rest joined in. I see it at work and I also see it on-line. Anonymity and lack of accountability also enhances the effect.

Whether the instigators are real or bots doesn't really matter because they "gave permission" to the rest to misbehave.
