Are there times when it is justified to fight?

I say that there is because if you are fighting for rights than it is ok. If you are fighting just because for no reason than its not ok unless you are fighting in MMA. That is ok because it is a sport. You can never really fight without violence because eventually over time you will explode and rage on the person. You could fight peacefully by staying calm and not yelling. I would fight for more freedom in one of my classes. I would talk to the teacher and if I didn't "win" the fight I would ask for a class switch. I would fight for it because I feel like the teacher doesn't let you do anything. The teacher before didn't have a seating chart, this teacher does. I wasn't here a few days but I helped a lot for one day in my group with a project and I still have to do one. There is not enough freedom for us and I don't like it.
