The purpose of communication is to seek clarity. All of us have our own perspectives and that is the reason we need to communicate to align.
Conflict is inevitable when two or more people are talking about things from their own perspectives, and that's where arguments come into the picture.
More often than not we believe in our point of view and sometimes we assume another party point of view. Hence, we will try to “win” the conversation by changing other minds by persuasion, bribery, threats, and other tools of force.
