I love arguing.  I do not argue in malice.  It is more of a debate.  I have taken up stances I do not agree with just to debate and have some fun, to keep people on their toes.  The key to arguing is not trying to convince the other person they are wrong.  That rarely happens.  It is all about will power.  Someone is usually right, and someone is usually wrong, but that is not the point.  The point is being able to stand up for yourself and say what you think regardless of whether it is popular or not.  Friendly debates help hone in the skills needed for when it really counts in life.
