Bully's are not strong, but weak minded individuals. That is why they feel the need to pick on others.
This is another common misconception about bullying. Bullies may be bullies because they are trying to deal with their own issues and are taking it out on others, but that is far from the case every time. Many bullies are also victims of bullying, and many bullies don't realize that they are being a bully.
Ever heard the line, "I was just joking"? That's the truth for some of them, they didn't intend for things to go as far as they did or didn't realize it was hurting the other person.
Any time you try to shove one reason onto a broad issue, all you do is make yourself look foolish.
Well turning a blind eye to the BS wont help either man.
Making the bully look like an idiot or picking a fight with them won't help either.
If you want to stop bullying, there's a few good options.
1) Stop doing whatever it is that you're being bullied for. This is the most simple solution. If you can't stop then ignore this.
2) Confront the bully, but not in a violent or antagonistic way. They may not be aware that what they are doing is bothering you. If they don't stop after you do this, move on to the next point.
3) Ignore the bully. If you stop responding to their taunts, they'll lose interest. If after a few weeks they don't stop, move on.
4) Involve teachers/parents/friends and ask them for their support. At this point you have taken every reasonable action against the bully that will not get you in trouble. Teachers/parents have much more authority than your friends and will be able to help you far better.
Violence may stop a bully, but it may also make things worse. Not even counting that you can be punished for retaliating.
