There is a big difference between arguing about something you disagree with and discussing it rationally. You may be feeling irritated and angered by someone's recent comment to you, and you may react in an angry way if you don't monitor your own emotions and the things you say, dear Scorpio. If you discuss this rather than fight about it, you have a very good chance of convincing the other person that you are right! It's all about your tone of voice and the way you present your point of view.
