I do not like fighting (see The Art of Fighting Without Fighting). To me fighting is, well, fighting; hitting, biting, blows, yelling, screaming, tricks and tactics specifically to do harm of some nature. I can understand that some people may equate sparring or boxing or MMA matches to fighting, but this could not be further from the truth.
Contests of the sort seen on the UFC are games and tests of specific skills. There are rules and referees, and doctors ready. While one or both opponents may intend to hurt the other, there is no ill will, or there should not be. They should seek to test of their metal, not vengeance.
I train to learn the intricacies of the art and science. It is much like learning a free flowing dance, with precise movements and intentions. It can be used in self defense, in a fight, but the people I train with and teach wish to avoid a fight as much as possible. We know the possible outcomes. I would say that most do not like the idea of fighting. Sparring can be fun, as can a more robust competition. But these are not fights.
I wonder about the kind of person that would go to some martial arts school and say, “I love fighting.” Do they really? Do they know what they are saying? Do they comprehend the distinction? Is that the kind of person that you would want to train? I think I would not. If they really like fighting, how quick would they be to pick one, one with me or one of my students no less. I would not want to risk any of my students or myself, and I would not want to give away useful secrets to an individual that may be inclined to use them unwarranted. In a fight, there is always a victim.
