I don’t get any impression of anyone teaching their children about bullying.
The parents of bullies are likely to be bullies, themselves. And so are likely to view that behaviour as acceptable.
Other parents are bullies, and expect their own children to just cave in and tolerate bullying, from anyone and everyone.
Spoiled brats bullied their way through childhood, and go on to expect to bully their way through adulthood.
Many people bully their spouses or partners.
I’ve seen people bully their neighbours over incredibly petty grudges. Including that the target simply wouldn’t be the bully’s personal friend.
There is bullying in education, from primary school up to university.
I recently witnessed a health care “professional” bully a patient.
I have encountered people who will start openly bullying, in the first conversation upon meeting a new acquaintance. In situations that were supposed to be about light socialising.
In any situation with money involved, you can expect bullying.
An employer will bully employees.
Employees will bully their coworkers.
I’ve seen businesses try to bully prospective customers.
The problem here is in your question.
People do NOT teach their children not to bully. And do NOT teach their children to intervene when witnessing bullying, up to, and including violent crime.
Parents very often teach their child to either BE bullies, or to look the other way, or to engage in victim-blaming.
And it often escalates to worse than looking the other way to bullying. See somebody being physically assaulted on the street? Pull out your phone and take a video. Not to aid the police in apprehending the offender(s), but just because it’s exciting to witness violence.
