Conflict is a part of human nature, as each and every person is a unique individual, and there in will always have an opinion that will be based on how their life was lived, and how they learned to be who they are.
If the above is true, then two people will always have something that they stand differently on, and if the degree of passion they feel about that subject is great enough, then a conflict will arise in their interests and they will argue.
But not all arguments are bad. Some are good, and let both people know that they are strong and will stand up for themselves. In this, we learn about each other through our conflict which makes us stronger better people. Even if sometimes, the arguments can lead to bad endings.
To stand up for your beliefs is a great strength some people search for while they live their lives. To sit idly by and let others tell you what your beliefs should be, is the way many have to live to survive.
But if you let someone else live your life, is it really a life at all?
In this, arguments can be a strength. But if one let's hate into their passion for their stand, then the argument weakens them. To argue is to stand for yourself. To hate is to fail at supporting yourself stably and in a strong way, and in that, an argument becomes a tool of the weak.
These are my thoughts on this.
