I would like to put a different slant on this topic. I feel that Karate has lost some credibility due to the fact that there are Dojo's that are flooded with kiddy Karateka's. I believe nothing brings the reputation of a MA down more than having 8-year-old kids running around with black belts. Offcourse that is not limited to Karate, but also other arts like TKD. At least I can take comfort in knowing that there are no students under 16 in my dojo who hold a black belt, and by god they have had to train for a long hard time to earn it.
