yeah I'm sorry but I really can not agree with this whole fatalistic "bullying is going to happen no matter what you do, so just throw your hands up and hope that you're mentally / physically strong enough to endure it" business. Even from my own limited experience of being in many different schools and school environments (around 6 relevant ones, public, private, etc), I can say with certainty that the scale of the bullying was not even close in some situations to what it was in others. Was there still some sort of "bullying" in the most technical sense of the word? Sure, but the scale to with it affected people's mental and physical health was enormously different than situations at other schools. Not all bullying is the same, and the fact that certain areas have far more of a bullying problem than others is a testament to its preventability. Bullying can and should be mitigated.
The victim is not at fault in any way, shape, or form. Some of you have talked about the most serious cases in which bullying leads to suicides and shootings, and maintained that this was because they were "psychologically unbalanced" anyway. This does not excuse the behavior of the bullies. If you give a dose of poison to a random sample of 100 people, and it's lethal to 50% of them, it is not the victims' fault for being too weak, or too old, or too unhealthy to survive the dosage. In cases where bullying is the direct cause of suicide, bullying is the problem - whether or not there were other factors that led to it.
Bullying is not a case of survival of the fittest. Every student (and for that matter, every person) should not have to be exposed to bullying and harassment, and this harassment should not be viewed as some sick ritualistic rite of passage that weeds out the psychologically and physically weak and strengthens the rest (p.s. it doesn't). I know that I've been extremely fortunate to not have been bullied to the scale that others have been, but even the relatively small amount of bullying I've dealt with has had lasting and destructive effects on me physically and psychologically. Bullying is a huge part of why I have as severe of anxiety-related disorders (body dysmorphia, anorexia, actual OCD), and I refuse to forgive all of the bullying that I experienced just because it's made me have to fight through these challenges (and tbh I still do).
the interwebs I think the point you brought up about sorting people into groups based on their performance in school is really interesting, because it's a situation I've been in too. I was sorted into an advanced group around 6th grade, and I've had classes with the same group of intelligent and (mostly) great people ever since. All of the bullying and harassment problems I've ever had came from the other classes that weren't divided that I was in. So, on the surface, this seems to be really helpful.
However, the problem is that the bullying doesn't go away, it just shifts the target. Not everyone can be sorted into a high-acheiving group, so the focus of the bullying just shifts from the kids in that group to the next available target. While it makes life more comfortable for the most intelligent (and I guess probably the most likely to be picked on) group of kids, it doesn't really solve the systemic problem. The fight against bullying really needs to focus more on adequate punishment and supervision rather than on expending resources to protect only the most likely victims.
