The primary purpose of combat skill is the defense of oneself or others for whom one has assumed responsibility. I'll expect you to be consistent, and comment upon the immorality of exhibition boxing.
Exhibition boxing (and wrestling and the like) is not (normally) done with the intent to irreperably injure the opposing party, which is the purpose of combat.
So I don't need to take up your challenge since there is no parrallel in the world of legitimate prize-fighting.
