There are two related but different things here. Social pressure to conform to expectations, and cruel behavior. Both are often called bullying now. 

Example of the first one is lets say you are a really annoying kid. Maybe you are an only child or have parents  that are similar. Not a bad kid but just not good at not talking over people or picking up social cues. It would be to your detriment to never experience peers chiding you or pushing you to not be annoying and learn social skills. If you never have to figure that out you end up with a personality that makes succeeding in life difficult. 

Example of the second is the same annoying kid, and he is ribbed for say not understanding when people don't want to talk about his interests, and he actually learns to moderate that and pick up on cues, but is still excluded and isolated by people for years because they think its fun. Or these people then proceed to go out of their way to make him miserable. That's very bad.

I agree with you. Picking on a kid is part of tribal behavior to reinforce what’s acceptable behavior.

We removed the ability of one kid to punch a malicious actor in the face though, and that’s created issues in society from my POV.

If Mike punches John in the face because John said, “Mike is going to be last because he chunky,” Mike over reacted.  Hard love would say, “Johns a jerk, but if you don’t want to last picked, maybe be healthier.”

But if every day John follows Mike and calls him a “chunky monkey” day after day, Mike should tee off on John, and when John goes to cry, that same hard love would be, “you pushed him too far and you deserved it.”

That serves to let Mike know what’s acceptable in society, and John to know you can’t push people to a breaking point and everybody’s point is different.

Now, we hold anti bullying seminars, you punch your bully and get suspended, or you bottle it up and become a school shooter.
