the thing about karate (and im sure youll agree with me) is its a crapshoot .... some schools turn out very skilled blackbelts, and other schools turn out chumps (ie they give em belts to keep em paying)
i never judge anyone by their belt, only by their performance
Yes. Originally the idea was, you earned black belt once you demonstrated a certain level of applied fighting ability (through actual fights with instructors and other students), in addition to technical ability demonstrated through kata. Some schools in the United States, started looking at technical ability alone, as it was easier and safer for them to practice non-contact or semi contact. They could get more kids and their parents in the doors. It was more profitable, thus the number of sport oriented touch schools.
In sport, any minor hit is usually a point, but when you practice full contact, the same attacks used in most other martial arts are demonstrated to be most effective: thigh kicks, roundkicks, front kicks, etc. Same as in Thai, except in karate the power is built from the hips, whereas in thai it's more of a step to the right followed by the kick. The karate method of generating power from hip shifting is not something you can do effectively without practice, but it's more efficient in the end.
5 year old black belts are just rediculous. As I said, these kids are being awarded blackbelt on the basis of their technical ability alone, whereas in legit schools it is awarded on actual fighting ability, not politics or anything else. In Okinawan schools, you actually have to perform physical task like lifting a 75 pounds over the head 25 times before EARNING a ranking because they recognised the importance of a certain amount of strength in real applied fighting. A 5 year old can't do any of this. His belt is based purely on katas/technical proficiency. Guys like Oyama (who was a Japanese nationalist despite being born Korean) saw the state of things and created Kyokushin in order to restore Karate to it's original purpose of being a serious fighting art and not a sport. But really, any legitimate school teaching Okinawan karate especially is no different because they never strayed in the first place.
