MA training is hardly college.
You are misunderstanding the point.
Its a hobby for a majority of people. Nothing more no matter how much you want to believe your a human weapon.
Of course it's a hobby. When I train in Military Saber & Singlestick, it's for fun and because I think it makes my knife-work better (which is, also, mostly a hobby), not because I expect to get in a duel with Cavalry Sabers.
BUT if you keep training and not worry about the rank well guess what the rank will come on its own in due time regardless
The point being missed is that writing, "if you just want a black belt, I can mail you three" is completely off the mark and, frankly, a bit condescending. The goal of a "black belt" is not about the piece of fabric, it's about what the awarding of said fabric recognizes about the holder. It's a tangible recognition of skill from a respected authority (the instructor). It would be the same if, instead of belts, the instructor awarded lapel pins, shoulder or breast patches, different colored boxing gloves, or nothing more than an actual certificate. It's the instructor, institution, or authorizing body standing up and saying to the world, "We certify that Joe Blow here has XYZ skills."
And, no, sometimes not worrying about rank and continuing to train
WON'T make rank come on it's own. It didn't in the PhotonGuy's case. What did come (we assume) is more skill. Yes, if you're dedicated, moderately talented, and have good instructors then, generally, skill will naturally grow. But that's no guarantee of recognition of said skill.
Now, I know that some people will say, "who cares if anyone recognizes my skill?, as long as I've got it, that's what's important." That sounds nice and all, but it ignores actual human psychology. The human brain doesn't work that way. Humans, particularly males, crave recognition. It's often an important element of furthering the "ultimate goal" of attaining more skill. Human Resource departments and good Managers the world over have figured this out. They've found that giving out "Recognition of Achievement" awards, or even just a simple pat on the back and and 'attaboy', is a great way to help motivate employees.
Yes, it's true that some people "buy the belt" just so that they can boast or have people believe they have skill which they do not. But, to be honest, they're actually a minority. Most people in my experience actually want to learn the skills but they need to have it recognized too. It's just a basic human need.
