Have we been doing this all wrong?

There was a period some time back, when pushing positive reinforcement was all the rage.

Now we have multitudinous campaigns to end bullying.

Pushes to improve social behaviors are a good thing, I believe, but I think sometimes the masses take the wrong approach.
It bully shaming the right way to go, really?
Kids learn their behaviors.
Frequently bullies don’t understand how they are wrong. By the time they get it, the behaviors are ingrained.
What makes more sense to me is educating all children about bullying, various character types, various mental issues, etc.

Besides that, I think we should educate children how to be better equipped to face being emotionally pressured, shamed or frightened.
Crying about bullies has become a sort of new type of bullying.

Children these days have issues understanding what is bullying, and what is expressing an opinion, or a simple choice.

What do you think? Can we do this better?
