I want to set one thing straight excessive bullying is in no way shape or form okay. When someone tells you to stop, or leave them alone, you better do it. However some bullying is, in my humble little opinion, a good thing. It can teach people how to stand up for themselves and assert themselves as people. Life is going to do the same thing but it is not gonna take it easy on you, and if you don't know how to stand up for yourself then you will be screwed. Now don't get me wrong calling someone the n word, the f word, or any other racial slur is not okay unless they want to be called that and have said explicitly that they want to because that is a form of bullying that I do not like. I was bullied a lot throughout high school and every time I stood up to it and told them to leave me alone, and it has prepared me for what I deal with now on the regular basis. However don't ever push someone to the point where they don't feel safe or want to kill themselves.

tl;dr
a little bullying is okay, making people want to kill themselves not good.

I can't think of anything profound to add right now, but I will say that bullying is generally a bad thing. The main problem with genuine bullies, versus friendly joking around, is that they don't stop when you ask.

Just make sure if you are bullied or see someone get bullied, nip it in the bud right away. Best way to do that is to get an adult.

Yeah, sometimes that'll make it worse and they'll just get mad at you for telling on them. So be cautious.

I've been bullied for about half of my life. It only really stopped fully last year. In that time I've learnt a lot.
First: It's not fun.
Second: Parents/Adults will tell you BS. I've been told every tip in the book, and it's all BS.
"It's because they're jealous of you". Why? I'm smart, but not the smartest. I've a good life, but not the best. So why are they jealous?
"Just ignore them". They continue. Sometimes it makes matters worse: they're not getting the reaction that they want from you, so they get worse.
"Fight back". I like my face the way it is, thank you very much.
"Tell the teacher/adult". Sometimes it works, other times it just gives them a reason to bully you (not a real reason, but most of the time, you're dealing with idiots)
etc. etc.

When I was being bullied, even people who I thought were my friends turned on me. Eventually it lead to depression, lose of faith in life, and getting close to suicidal. Not good.

lulz Bullies.

They're not jealous: they're insecure. They don't want your life, but they don't want theirs more.

A bully acts on his failing self-image, brought on by a tumultuous domestic life, with aggressive verbal or physical assault on people he feels are inferior to the status quo (in childhood, a judgment based on what vapid, egotistical, middle school socialites think). He wants to validate his existence on the only thing he understands: the physical or social hierarchy established by a society of ignorant, unhappy people. It's a concept that's easy to grasp when a person needs unsubstantiated material to make another feel like ****, because angry people don't often react on intelligence, so they can't think of anything better.

Children are too naïve to understand that their self-esteem isn't based on how other people feel about them. Happiness, confidence, and success comes from a healthy perspective of oneself. Your parents, teachers, employers, friends, or lovers aren't going to wait for you to start feeling good about yourself, and the same goes for people who think you're garbage.

Bullying is something young people commonly battle until they're in an adult setting. Then obvious abuse turns to a more obscure, deep-rooted psychological and emotional conflict... then it's called "a relationship."

The truth is, humans are horrible because they're apathetic. Hopefully someday, you'll grow wise and honest enough to discern what's really important and surround yourself with people that matter who feel the same way.
