I understand where you are coming from, but the Founder of the Art, Choi Dojunim only died in 1986, so I really don't think it was pride keeping them apart more than, perhaps, arrogance and lack of integrity.
Far too many students of Choi Dojunim, and their students, inflated their rank and tried to add material to a style they had not fully learned...
This is why there is no single system...the problem is that it can be interpreted in an open fashion - usually incorrectly - even most of the core concepts are misunderstood...
There is, never the less a single current Dojunim, Chang Chin Il. And more fortunately, many of the "offshoot" styles tack something in front of the word Hapkido, so at least the public can know what they are getting in many cases.
I understand that you are proud of your lineage. I am just as proud of mine.
As for inflated rank, I am not aware of any in my lineage (Choi, Suh Bok-Sub/Won Kwang-Wha, Lee H. Park, Mike Morton, me). In any case, I'm sure all of these people have at least as much certification as Choi himself had
I'm sure our opinions differ, but in mine: Choi didn't know hapkido. He was just the most significant contributor to several sources of technique that, when combined became Hapkido.
To use a metaphor, Choi is the beef in a beef stew. But a bowl full of beef is not beef stew. It isn't until you add the potatoes, carrots, etc., and let it simmer that it becomes stew. Ingredients vary slightly and proportions — hence the many varieties of hapkido.
You think your stew is best because it is full of Choi beef and, if I understand correctly, very little else. That's great.
I think OUR recipe for stew is better. No disrepect intended for Choi — he was a critical and essential ingredient —*the catalyst for hapkido becoming hapkido.
But I think the kicking added by Kim Moo-hyung was a GREAT addition and that those hapkido style that DON'T have the dynamic kicking are missing a great ingredient. I think the full-circle throwing added from the judo backgrounds of many of the key figures in my lineage is also a GREAT addition.
I think the beef we got from Choi is some good stuff. Meaty, very little fat. I'm sure if you spent some time on the mat with Lee H. Park before he passed away, you would have been impressed. Everybody who met him was. Very much.
You can drop words like arrogance and integrity, but I think my instructor and his instructor before him (Park) had none of the former and plenty of the latter.
As for a unified hapkido — I think it's a great idea, but I don't think everybody will drop their curriculum in favor of ours and we surely won't be dropping ours to conform with anyone elses
It isn't that we are arrogant; we love our stew recipe and think it's the best. Adopting one we don't believe in would show a lack of integrity.
Just remember we ARE part of the hapkido family (and at the senior side of the family tree, fwiw) — and all the redefinitions and wishes won't change that. I hope there is a mutual respect between us.
Wishing your and your branch of hapkido all the best.
Respectfully yours,
