This is what I've been saying. Only two realistic options exist and anyone interested in this topic has a simple choice to make. If John P. earned his ranks, then those that ranked him should proudly say so as he has gone on to develop a successful system that is well received from those actually training in it.
Once again, skills are earned. Rank is issued and responsibility is assigned or taken on.
Not all officers enlist and go through the ranks of private, corporal, or sargeant. Some go to officers school and graduate as officers. Corporate officers and CEOs do not get to their position very frequently by starting out in the mail room or even for being exceptionally good at the company's primary business. The CEO of Red Lobster, for example, probably wasn't a lobsterman and certainly wasn't required to work all of the restaurant positions in order to climb the corporate ladder. He or she was probably brought in from somewhere on the basis of business accumen and probably got started by going to business school.
I remember when Radio Shack brought in Len Roberts as the new president back in the late eighties/early ninties. He came from Shoneys and had no background in electronics at all. As I recall, he did a good job. I left when he was still president (perhaps he still is) so I have no idea what Radio Shack thinks of him now.
The reason that officers in the military are not always former grunts and that the corporate head of Harley Davidson probably didn't start off as a motorcycle mechanic is because the skills needed to be an officer or a corporate head are unrelated to the skills needed for being in the trenches or on the front line.
I strongly suspect that there was never any point in his life that Cus D'Amato could have ever beaten Mike Tyson in his competitive years. But he was able to coach Mike Tyson and train him to become a champion. And most of the best football coaches are not former superstar athletes. But they can coach a team of superstar athletes and coordinate their efforts so that the team succeeds on the field.
If he didn't...well, then there is the other option for those folks to consider. As mentioned multiple times, it is a moot point at this juncture.
What, that he bought his rank? Actually, there are several options to consider. Again, the ability to put together a system and an organization are a different skill set than those of being a hotshot on the mat. Asking a tournament champion to systematize the technical elements of a martial art and to put together an organization to spread that art will, in most cases, yield less than satisfactory results.
GMP's skills as an organizational head and as the founder of his system are a separate skill set from those of being an exceptional MA-ist. Which is why I prefer to judge the man based on the quality of his system and of his organization.
As I said, his rank isn't going anywhere. Chances are, his organization will outlive him. So how good is the organization and how good is the system?
If you don't like that he called it hapkido, get over it. He's not changing the name. I'm sure that Ferrari drivers had the same complaint about the Pontiac GTO. Perhaps if you wait long enough, the CHKD organization will go the way of Pontiac. But be perpared for a long wait; Pontiac was around for over eighty years.
To be clear, lest anyone think that I am giving approval to the kind of rank gymnastics that it seems that GMP and his senior engaged in, I am not. I feel that such rapid promotions
always cause friction and undermine the efforts of those who receive such promotions. The only people who care about how quickly you were promoted and to what rank are other MA-ists. Your students will not care, particularly if your system is decent. Nobody cared what rank Bruce Lee was. Nobody cared what rank Funakoshi was either (it was fifth dan, in case you were wondering). Nobody cared what rank Choi Yong Sul was for that matter. And I suspect that GMP is smart enough that he could have accomplished everything that he has with CHKD even without a grandmaster rank.
Rank inflation has been an issue in the martial arts for decades. There is no good reason to undermine what you do by engaging in it. So don't do it.
