Are there times when it is justified to fight? For what? Can you fight for something without becoming violent? How can you fight peacefully? What would you fight for? How and why?

there are times when it is justified to fight like when you standing up for what you believe in if you believe in something strongly you have every right to fight for what you believe in thats the way the human race works without the ability to express show we feel the world would be so wierd like i cant even describe how wierd that would be we would have no rights basically clones of one another but i think that we souldonly fight for what we believe in and not some nonsense fight i think that that is wrong you can fight without being violent but im not saying that you have to  be  peaceful again its kind  of how the human race works were tough
from when we are young to stand up for what we believe in and to share but what if we strongly believe in not sharing what should we do what we were taught to fight for what we believe in
