The problem with shame is that the people who use shame as a tool do not understand how to use it conservatively.

You see, they shame for playing music in public. Okay, great.

But they also shame for your weight, your sexuality, the color of your skin. Your job, your hobbies, your family. Your clothing, your skin, your hair.

And now, shame, as a tool, has been worn down to its bones. Of course then society at large begins to reject it.

Yeah, agree. It has been overused, and it's good that that doesn't work any more. I'd like the line to be drawn just a little further back, though, please ;)

I think the primary difference is shaming someone for behavior that impacts others and shaming someone for behavior that is none of my business.
