It is my belief that blood sports should be banned. They can cause injury, scars, and even death. In September 2001 and December 2004, the MMA did a study on mixed martial arts. Of the 171 matches they studied, 69 (40.3%) ended in injury for at least one player. Do we really want our youth, or adults for that matter, playing such violent sports? And what happens when a child brings his new "talent" home? There could be major injuries caused because a child does not know that these things can hurt people. Yes, these sports do teach some amount of discipline, but they also are teaching the 101 ways of killing a person with your own two hands. If you want your child to learn discipline, put him/her in a sport that does not teach violence.
