As to this whole bullying issue, I that is, perhaps, an oversimplification of the point that Epimetheus is trying to make. The point is not that kids should be bullied as a necessary part of socialization, but that kids need to be exposed to a variety of social interactions, including negative ones, in order to acquire the social skills they will need as adults.
They need to spend at least some time in environments and contexts which are not rigorously controlled by their parents in order to learn how to be self-reliant.
They need to individuate from their parents by interacting with people who have no connection to their parents.
They need to learn that sometimes life isn’t fair, that some people will be hostile to them without cause, and that they need to develop mechanisms for coping with such things, both intellectually and emotionally.
They also need to encounter people who are completely different than they are, who they would never have had any cause or occasion to talk to or know anything about within their own family environment, and from whom they can discover completely surprising things about the world and about themselves.
They need to have secrets. They need to try things that their parents wouldn’t approve of. They need to learn some things the hard way. My parents were right in about 95% of the advice that they gave me, but I didn’t believe they were right until I tried some things for myself. true learning must come from experience, not just from authority.
