This kind of mob "justice" against people will destroy society. Stop promoting it.
What we have is the logical extension of the social justice, or SJW, movement. Which even 2 years ago, in my recollections, would have been met with utter disdain. Somehow we've arrived at a time when social justice has a new-found legitimacy and few detractors still speaking out about it.
To me this is scarier than a mob, who usually have a figurehead around whom they rally. The SJWs have been building their seat of power on the shoulders of social media celebrities.
This is Huxleyan populism. People 'follow' others from their sofa, they 'like' things without critical assessment, bolstering support for an ill-defined cause based on memetic catchphrases and sound-bite signals.
