AIBU to think that many of those parents who push back against schools and their rules are completely oblivious to the damage they're doing to their children?
The children who do the best are those whose parents instill in them that they should conform. Yes, that will cause difficulties at times. Yes, there will be things they don't like. But that's life. That's how children develop resilience.
