Casey:
I totally understand that you identify with my concern, but I would like to address the questions you posed so I don't just sound like a jerk

.
1. "What standards make a person 'qualified?'"
-If you are teaching under an organization, your dan certificates would be the standard. Believe me, I know how easy it is to forge those documents (remember, I'm a graphic designer) and I have caught so-called masters red-handed in their forgery. However, at least a teaching certificate is something tangible.
If one is totally self taught, well that opens a huge can of worms. Let me just say this point, if a person has no one else to determine thier qualifications or in the least judge thier performance (instructors, competitions, peers, etc.), how can you know if you are qualified?
2. "...define "skill;"
-Skill can sometimes be subjective. I have taught people who in thier first month have surpased others who have trained for years. I define skill as a fundamental proficiency and basic knowledge of the weapon. If one doesn't know why your hands are placed here and your feet are placed there, how can you teach it?
3. "...Who made you the keeper of the standards?"
- Obviously, I am not the keeper of standards for everyone, but I am at my school. Being an instructor, I feel a certain responsibilty to ensure safety among practioners and to help propagate the arts. I have trained with many people over my many years and have seen things that I liked and thing I didn't. Every school, regardless if they are in the same organization or an entirely different art, has thier own way of doing things. A stance that may be OK in one art, may be wrong to another. However, I believe that all arts share the common understanding that safety is extremely important and can not be put aside. Common sense can not be abandoned simply because this "trick" would look cool or to better line my pockets.
In conlusion, I have made it a point to help foster friendship and comradery between different arts and schools. With this aspect, I have had to many times hold my tongue so as not to accidentally offend someone. I feel that my concern here goes beyond the risk of offending; it is a matter of right and wrong. Whenever I hear someone tell me that they do very dangerous things with a sharp weapon, I politely advise them not to. If that person wants to win the Darwin Award, there really isn't too much one can do but I feel I should at least warn them. What offends me is imposters teaching these very dangerous habits to students who don't know any better. A teacher with no sense of responsibilty is not a martial artist but a con artist.
Thank you
