Mixed Martial Arts and Jeet Kune Do need to be banned because they are not a true martial art. MMA is a fighting sport like boxing and wrestling; Jeet Kune Do is developed by Bruce Lee who never finished learning Kung Fu.
People who do MMA call other dojos or dojangs who teach real martial arts McDojos. The Olympics are not helping either because they show more sparring instead of forms or weapons.
Jeet Kune Do is just a made up Martial arts without any forms. Real Martial Arts have forms and sparring.
Martial Arts are for self-defense not for beating each other up in the street or in a grudge match. Tournaments are fun, but they should remain true to the real martial arts not the fighting sport, MMA or the made up Jeet Kune Do even in the Olympics.
Without Mixed Martial Arts and Jeet Kune Do, people wouldn't start street fights or school fights as much. The police, teachers, and principals would not have to break up the fights. The police would be able focus on stopping real crime and dangerous driving. The teachers would be able to focus on teaching the children. The principals would be able to focus on the school.
People would have to go to the places that they called McDojos before to learn martial arts if MMA and Jeet Kune Do were banned. The real martial arts' dojos and dojangs can take over the MMA and Jeet Kune Do studios! Everything would be better off without MMA and Jeet Kune Do!
