Thanks to so many people in this thread for thoughtful discourse and helping me on my journey to understand the issues better.

I just watched The Outrage Machine, which is a short (12mins) documentary that can help us learn.

It talks about trolling, the yearning to judge, public shaming, cancel culture, mob mentality, moral superiority, harassment, abuse.
