There's a peeking order in life. I bully you, someone else bully's me etc. etc. Sometimes bullying goes over the top and needs to be corrected. Bullying teaches people to stand up for themselves. We learn to accept criticism from peers. We learn how to respond to criticism. I hope I explained myself. It's easy to say bullying is wrong, stop all bullying, but all of us has survived some sort of bullying and it made us stronger.
