I kinda agree with this.
Without conflict as a youth, how are you to understand resolution and how to deal with people you don't like or disagree with? Harassment and attitude are not the same. I mean, I would love the world to all get along, and sing happy songs all day.. but that shit isn't happening. Kids are little shits.
This is also why my kid will not be allowed any social media anything OR a cellphone until they are 17.
