Some very good pionts!! I have been teaching 24 years and training over thirty. in 24 years I have only promoted 5 people to Black Belt and no one under the age of 16. 8 and 10 year old Black Belts are a joke. Not only can they not defend themselves at that age they don not have the maturity to be a proper Black Belt. I was trained that you are a Black Belt in every part of your life not just in the dojo. I also agree you should train for reality and tournaments should test what you have learned. Years ago in the old AKA tournaments, it was common to see knockouts. Now if you rock a persons head back you get disqualified. You can't even use groin kicks any more. My belief is if you want to keep em, you better learn to protect them. Nothing teaches you to learn to block properly better than a kick or two in the groin.
