UGCTT_Fillthy - If you think BJJ is a combat sport, then a black belt probably doesn't mean anything beyond 'really good grappler' (ie Lloyd Irvin)
If you think BJJ is a martial art, then a black belt speaks more to the overall quality of the person (ie Rickson Gracie)
I don't think either is right or wrong, but personally, I side with Shen on this one.
Whether one likes it or not, there is no debate that historically morality and character builing are central concerns of most martial arts. If you read the autobiographies of or biographies about famous masters, this is the unifying thread that unites them beyond the different methods each advocated. They all felt martial arts had to serve a greater purpse than mere fighting and that purpose was to improve people's lives and thereby improve their communities:
Kano, Founder of Judo ("All things connected with [Judo] should be directed at it's ultimate object, the benefit of humanity")
Funakoshi, Founder of (Shotokan)Japanese Karate ("The ultimate aim of karate lies not in victory nor defeat, but in the perfection of the character of it's participants")
Doshin So, Founder of Shorinji Kempo ("Live half for yourself and half for others")
Ueshiba, Founder of Aikido ("The purpose of training is to tighten up the slack, toughen the body and polish the spirit")
--And that's just the tip of the iceberg among Japanese martial arts masters.
In the past you had to prove yourself of worthy character toeven be accepted as a student of the matrial arts. Instructors were picky about who they chose.
These days, pretty much ANYONE who walks in the door and can pay will be accepted. That is a HUGE change in the way martial arts are practiced. Huge.
