I think if you are stirring up stuff, you shouldn't be surprised when someone tries to hit you. While I agree with
>>3, you shouldn't be starting anything if you can't back it up, talk your way out of it, or actually fight.
Fights break out almost weekly at my school, I am sure you're life will remain intact if you get in one or two fights. The only negative thing, would the ISS would be recorded on your record for all future colleges and jobs to see, but if that doesn't bother you. Then fight all you want and do anything else.
While fighting isn't healthy, it will not actually kill you unless your opponent gives a nasty headshot. I can't tell if you are asking us to do something about ALL school fights or help you out with your own. But either way, I will give you some advice.
If it is within your own community, I would suggest getting in contact with those in your area and teaming up with teachers, principle and maybe even the police in order to do something the problem.
If you are talking about in general, I would suggest making some sort of "Anti-Violence In School's" campaign with various people all over the world.
I hope that this was helpful...
