I enjoy arguing with people. (Debating, discussing, Im not talking about getting mad.) I said that Harry Potter is a great book and my roommate says they are bad and he doesn't approve. I think that he is wrong but won't listen and he believes he is always right. How do I convince him they are ok? Also, I have met a lot of people and when they argue they argue as if my opinion doesn't matter and that they are always right and it makes me mad that they can't open their minds. How do I deal with these people. Thanks for all you help!! (Also, I live on a christian campus/university) .
