Arguments can be both rational and irrational but they are quite necessary for various reasons. In every relationship there should be some space for an argument. People argue mainly when they have a difference in opinion and want their point to be taken seriously. Arguments can clarify your doubts and disillusions. It is always better to express your original opinions instead of just agreeing with what others have to say. People also argue when they face an intellectual hindrance. If there is something you do not believe or if questions arise in your mind regarding a matter you may start an argument with someone who is a staunch believer of the same matter.
